  • Tetranuclear zigzag Ag4 and Ag2Pt2 complexes supported by rac-Ph2PCH2P(Ph)CH2P(Ph)CH2PPh2 (rac-dpmppm)

    Tomoaki Tanase; Risa Otaki; Kanako Nakamae; Yasuyuki Ura; Takayuki Nakajima

    © 2020 Elsevier B.V. Reaction of AgOTf with a tetraphosphine, rac-bis[(diphenylphosphinomethyl) phenylphosphino]methane (rac-dpmppm), afforded [Ag4(rac-dpmppm)2](TfO)4 (3) which consists of zigzag-arrayed tetranuclear silver(I) ions supported by syn-arrangement of two enantiomeric (RR/SS) dpmppm ligands. Complex 3 readily reacted with XylNC (Xyl = 2,6-dimethylphenyl) to give [Ag4(rac-dpmppm)2(XylNC)2](TfO)4 (4), where two terminal isocyanides attach to the outer Ag sites. Complex 3 has been shown a good precursor for Pt-Ag-Ag-Pt mixed metal array as incubation of 3 with trans-[Pt(C[tbnd]CPh)2(PPh3)2] yielded [Ag2Pt2(C[tbnd]CPh)4(rac-dpmppm)2](TfO)2 (5). Two trans-Pt(C[tbnd]CPh)2 units are incorporated into the terminal positions in a site-selective fashion and the Pt-Ag-Ag-Pt tetranuclear core also adopts a zigzag array supported by syn-arrangement of two rac-dpmppm ligands. The d8 and d10 closed-shell mixed metal centers of 5 exhibited an intense photoluminescence at 534 nm, mainly from an unsymmetric triplet state generated by charge transfer transitions from ligand (acetylide π) to metal centers (Ag2 and PtAg s/pσ), 3LMCT, and to ligands (acetylide π* and dpmppm), 3LLCT. The present results provide fundamental and useful information to construct multinuclear closed-shell metal alignments by utilizing polyphosphine ligands., 2020年10月15日, Journal of Organometallic Chemistry, 925, doi;scopus;scopus_citedby

  • Palladium/Copper-catalyzed Oxidation of Aliphatic Terminal Alkenes to Aldehydes Assisted by p-Benzoquinone

    Saki Komori; Yoshiko Yamaguchi; Yuka Murakami; Yasutaka Kataoka; Yasuyuki Ura

    © 2020 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim The development of an anti-Markovnikov Wacker-type oxidation for simple aliphatic alkenes is a significant challenge. Herein, a variety of aldehydes can be selectively obtained from various unbiased aliphatic terminal alkenes using PdCl2(MeCN)2/CuCl in the presence of p-benzoquinone (BQ) under mild reaction conditions. Isomerization of the terminal alkene to the internal alkene was suppressed via slow addition of the starting material to the reaction mixture. In addition to the Pd catalyst, CuCl and BQ were essential in order to obtain the anti-Markovnikov product with high selectivity. Terminal alkenes bearing a halogen substituent afforded their corresponding aldehydes with high anti-Markovnikov selectivity. The halogen acts as a directing group in the reaction. DFT calculations indicate that a μ-chloro Pd(II)−Cu(I) bimetallic species with BQ coordinated to Cu is the catalytically active species in the case of a terminal alkene without a directing group., 2020年08月06日, ChemCatChem, 12 (15), 3946 - 3955, doi;scopus;scopus_citedby

  • Facially Dispersed Polyhydride Cu9 and Cu16 Clusters Comprising Apex-Truncated Supertetrahedral and Square-Face-Capped Cuboctahedral Copper Frameworks

    Kanako Nakamae; Takayuki Nakajima; Yasuyuki Ura; Yasutaka Kitagawa; Tomoaki Tanase

    © 2019 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim By using a linear tetraphosphine, meso-bis[(diphenylphosphinomethyl)phenylphosphino]methane (dpmppm), nona- and hexadecanuclear copper hydride clusters, [Cu9H7(μ-dpmppm)3]X2 (X=Cl (1 a), Br (1 b), I (1 c), PF6 (1 d)) and [Cu16H14(μ-dpmppm)4]X2 (X2=I2 (2 c), (4/3) PF6⋅(2/3) OH (2 d)) were synthesized and characterized. They form copper-hydride cages of apex-truncated supertetrahedral {Cu9H7}2+ and square-face-capped cuboctahedral {Cu16H14}2+ structures. The hydride positions were estimated by DFT calculations to be facially dispersed around the copper frameworks. A kinetically controlled synthesis gave an unsymmetrical Cu8H6 cluster, [Cu8H6(μ-dpmppm)3]2+ (3), which readily reacted with CO2 to afford linear Cu4 complexes with formate bridges, leading to an unprecedented hydrogenation of CO2 into formate catalyzed by {Cu4(μ-dpmppm)2} platform. The results demonstrate that new motifs of copper hydride clusters could be established by the tetraphosphine ligands, and the structures influence their reactivity., 2020年02月03日, Angewandte Chemie - International Edition, 59 (6), 2262 - 2267, doi;pubmed;scopus;scopus_citedby;url;url;url

    Zhenhua Wang; Xiu Wang; Yasuyuki Ura; Yasushi Nishihara

    Copyright © 2019 American Chemical Society. Ni-catalyzed decarbonylative cyanation of acyl chlorides with trimethylsilyl cyanide has been achieved. This transformation is applicable to the synthesis of an array of nitrile compounds bearing a wide range of functional groups under neutral conditions. The step-by-step experimental studies revealed that the reaction sequences of the present catalytic reaction are oxidative addition, transmetalation, decarbonylation, and reductive elimination., 2019年09月06日, Organic Letters, 21 (17), 6779 - 6784, doi;pubmed;web_of_science;scopus;scopus_citedby

  • Alloyed Tetranuclear Metal Chains of Pd4−nPtn (n=0–3) Scaffolded by a New Linear Tetraphosphine Containing a PNP Bridge

    Tomoaki Tanase; Miho Tanaka; Mami Hamada; Yuka Morita; Kanako Nakamae; Yasuyuki Ura; Takayuki Nakajima

    © 2019 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim A new linear tetraphosphine containing a PNP phosphazane bridge, rac-bis[(diphenylphosphinomethyl)phenylphosphino]phenylamine (rac-dpmppan), was synthesized and utilized to support a series of Pd/Pt mixed metal tetranuclear chains, [Pd4−nPtn(μ-rac-dpmppan)2(XylNC)2](PF6)2 (XylNC=xylyl isocyanide; n=0: Pd4 (1), 1: PtPd3 (2), 2: PtPd2Pt (3), 2: Pt2Pd2 (4), 3: Pt2PdPt (5)), in which the number and positions of additional Pt atoms were successfully controlled depending on the respective synthetic procedures using transformations from 1 to 3 through 2 and from 4 to 5 by redox-coupled exchange reactions. The 31P{1H} NMR and ESI mass spectra and X-ray diffraction analyses revealed almost identical tetranuclear structures, with slight contraction of metal-metal bonds according to incorporation of Pt atoms. The electronic absorption spectra of 1–5 exhibited characteristic bands at 635–510 nm with an energy propensity depending on the number and positions of Pt centres, which were assigned to HOMO (dσ*σσ*) to LUMO (dσ*σ*σ*) transition by theoretical calculations. The present results demonstrated that the electronic structures of Pd/Pt mixed-metal tetranuclear complexes are finely tuned as orbital-overlapping alloyed metal chains by atomically precise Pt incorporation in the Pd4 chain., 2019年06月21日, Chemistry - A European Journal, 25 (35), 8219 - 8224, doi;pubmed;scopus;scopus_citedby

    © 2019 American Chemical Society. Hexanuclear copper hydride complexes, [Cu6(μ3-H)2(meso-L4)3(RNC)4](PF6)4 (R = tBu (6a), Cy (6b)), were prepared by using a new linear tetraphosphine, meso-Ph2PCH2P(Ph)(CH2)4P(Ph)CH2PPh2 (meso-L4), and were converted into active catalysts of [Cu2(μ-O2CH)(meso-L4)(RNC)2]+ under the reaction conditions of formic acid dehydrogenation, where unsymmetric dinuclear copper sites supported by the tetradentate phosphine and isocyanide ligands were essential to demonstrate effective catalytic activity., 2019年06月05日, Journal of the American Chemical Society, 141 (22), 8732 - 8736, doi;pubmed;scopus;scopus_citedby

  • Palladium-Catalyzed Aerobic Anti-Markovnikov Oxidation of Aliphatic Alkenes to Terminal Acetals

    Saki Komori; Yoshiko Yamaguchi; Yasutaka Kataoka; Yasuyuki Ura

    © 2019 American Chemical Society. Terminal acetals were selectively synthesized from various unbiased aliphatic terminal alkenes and 1,2-, 1,3-, or 1,4-diols using a PdCl2(MeCN)2/CuCl catalyst system in the presence of p-toluquinone under 1 atm of O2 and mild reaction conditions. The slow addition of terminal alkenes suppressed the isomerization to internal alkenes successfully. Electron-deficient cyclic alkenes, such as p-toluquinone, were key additives to enhance the catalytic activity and the anti-Markovnikov selectivity. The halogen groups in the alkenes were found to operate as directing groups, suppressing isomerization and increasing the selectivity efficiently., 2019年03月15日, Journal of Organic Chemistry, 84 (6), 3093 - 3099, doi;pubmed;scopus;scopus_citedby

  • Tetra-, hexa- and octanuclear copper hydride complexes supported by tridentate phosphine ligands

    Takayuki Nakajima; Kanako Nakamae; Rika Hatano; Kaho Imai; Masafumi Harada; Yasuyuki Ura; Tomoaki Tanase

    © 2019 The Royal Society of Chemistry. Multinuclear copper hydride complexes were synthesized by using a triphosphine, bis(diphenylphosphinomethyl)phenylphosphine (dpmp). The reaction of [Cu(MeCN)4]PF6 with dpmp in 2:1 ratio in the presence of Me4NBH4 or NaBH4 yielded a hexanuclear complex, [Cu6(μ3-H)5(μ-dpmp)3]PF6 (1), together with a minor product [Cu8(μ-H)2(μ4-H)4(μ-dpmp)4](PF6)2 (2) in a very low yield. Complex 1 was also prepared from [CuH(PPh3)]6, [Cu(MeCN)4]PF6, and dpmp in 87%, but the yield of 2 could not be improved presumably due to its instability in solution. A tetranuclear complex, [Cu4(μ-H)(μ3-H)2(μ-dpmp)3]PF6 (4), was obtained from the reaction of [Cu(MeCN)4]PF6 with dpmp in 4:3 ratio, or that of [Cu3(μ-dpmp)2(MeCN)4](PF6)3 (3) and dpmp, in the presence of Me4NBH4 for both cases. The structures of 1, 2, and 4 were determined by X-ray crystallography, and the positions of hydride ligands were elucidated by DFT optimization. Complex 1 consists of a distorted trigonal anti-prismatic Cu6 core bridged by three L-shaped dpmp ligands and five μ3-hydrides, and 2 is composed of three edge-shared tetrahedral Cu4 units supported by four L-shaped dpmp ligands and two μ2-hydrides in the two outer Cu4 units and four μ4-hydride ligands in the central Cu4 units. The structures of two outer Cu4 units in 2 resemble those of 4, where a Cu4 tetrahedron is supported by two L-shaped dpmp ligands and one dpmp-κ2P,P′ bridge, in addition to one μ2- and two μ3-hydrides. Natural bond orbital analyses suggest that the hydrides act as glue between the multinuclear copper centres through electron-deficient delocalized bonding interactions, which result in partial electron migration from hydrides to CuI centres., 2019年, Dalton Transactions, 48 (32), 12050 - 12059, doi;pubmed;scopus;scopus_citedby

  • Copper-catalyzed regioselective chloroamination of alkenes with chlorotrimethylsilane and n-fluorobenzenesulfonimide under microwave-assisted conditions

    Masayuki Iwasaki; Jie Xu; Yukari Tani; Liyan Fu; Yuichi Ikemoto; Yasuyuki Ura; Yasushi Nishihara

    © 2019 The Chemical Society of Japan. A copper-catalyzed chloroamination of alkenes with chlorotrimethylsilane and N-fluorobenzenesulfonimide has been developed. The reactions were complete within 1 h at 120 °C by means of microwave heating. The present chloroamination proceeds with a perfect regioselectivity and is compatible with various functional groups. The preliminary mechanistic investigation revealed that the reaction involves a radical process. The utility of the present method was demonstrated by scalable, operationally simple and safe system., 2019年, Chemistry Letters, 48 (3), 281 - 284, doi;scopus;scopus_citedby

  • Tri- and Tetranuclear Copper Hydride Complexes Supported by Tetradentate Phosphine Ligands

    Takayuki Nakajima; Yoshia Kamiryo; Kanae Hachiken; Kanako Nakamae; Yasuyuki Ura; Tomoaki Tanase

    Copyright © 2018 American Chemical Society. Three types of tetradentate phosphine ligands with different central methylene chains and configurations, meso- and rac-Ph2PCH2P(Ph)(CH2)nP(Ph)CH2PPh2 (n = 2, meso- and rac-dpmppe; n = 3, meso-dpmppp) were utilized to synthesize a new series of tri- and tetranuclear copper hydride complexes. Reactions of meso-dpmppe or meso-dpmppp with CuCl/NH4PF6 or [Cu(CH3CN)4]PF6 in the presence of NaBH4 afforded trinuclear copper hydride complexes, [Cu3(μ3-H)(meso-dpmppe)2](PF6)2 (1) and [Cu3(μ3-H)(meso-dpmppp)2](PF6)2 (2), while a similar reaction with rac-dpmppe resulted in the formation of a tetranuclear copper dihydride complex, [Cu4(μ3-H)2(rac-dpmppe)2](PF6)2 (5). Complexes 1 and 5 further reacted with RNC (R = tBu, Cy, Xyl) to give [Cu3(μ3-H)(meso-dpmppe)2(XylNC)](PF6)2 (3), [Cu4(μ3-H)2(meso-dpmppe)2(RNC)2](PF6)2 (R = tBu (4a), Cy (4b)) and [Cu4(μ3-H)2(rac-dpmppe)2(RNC)2](PF6)2 (R = tBu (6a), Cy (6b), Xyl (6c)), respectively. Complexes 1-6 were characterized by ESI-MS and 1H and 31P NMR spectroscopy and X-ray diffraction analyses, demonstrating that a hydride ligand is located at the center of triangular Cu3 plane of 1-3, while two μ3-hydride-capped Cu3 planes are fused to result in rhombic Cu4H2 structures in 4a,b, 5, and 6a-c. Complexes 1-6 in CD3CN solutions notably showed high thermal stability and no reactivity toward H2O and CO2. DFT calculations indicated an interesting correlation between the Wiberg bond indices (WBI) of Cu-H bonds and their natural atomic charge (NAC), where the isocyanide ligands had an appreciable influence on the Cu-H interactions., 2018年09月04日, Inorganic Chemistry, 57 (17), 11005 - 11018, doi;scopus;scopus_citedby

  • Regioselective Synthesis of γ-Lactones by Iron-Catalyzed Radical Annulation of Alkenes with α-Halocarboxylic Acids and Their Derivatives

    Iwasaki, Masayuki; Miki, Natsumi; Ikemoto, Yuichi; Ura, Yasuyuki; Nishihara, Yasushi

    Copyright © 2018 American Chemical Society. An abundant and low toxicity iron catalyst has enabled regioselective annulation of alkenes with α-halocarboxylic acids and their derivatives. The reaction proceeds smoothly without any additional ligands, bases, and additives to afford a variety of γ-lactones in good yields. A proposed reaction pathway through radical annulation is supported by some mechanistic studies, involving radical clock and isotope labeling experiments. The present method was applied to the practical iron-powder-promoted synthesis of γ-lactones., 2018年07月06日, Org. Lett., 20 (13), 3848 - 3852, doi;pubmed;scopus;scopus_citedby

  • Templated Self-Assembly of Dynamic Peptide Nucleic Acids

    John M. Beierle; Yasuyuki Ura; M. Reza Ghadiri; Luke J. Leman

    © 2017 American Chemical Society. Template-directed macromolecule synthesis is a hallmark of living systems. Inspired by this natural process, several fundamentally novel mechanisms for template-directed assembly of nucleic acid analogues have been developed. Although these approaches have broad significance, including potential applications in biotechnology and implications for the origins of life, there are unresolved challenges in how to characterize in detail the complex assembly equilibria associated with dynamic templated reactions. Here we describe mechanistic studies of template-directed dynamic assembly for thioester peptide nucleic acid (tPNA), an informational polymer that responds to selection pressures under enzyme-free conditions. To overcome some of the inherent challenges of mechanistic studies of dynamic oligomers, we designed, synthesized, and implemented tPNA-DNA conjugates. The DNA primer region affords a high level of control over the location and register of the tPNA backbone in relation to the template strand. We characterized the degree and kinetics of dynamic nucleobase mismatch correction at defined backbone positions. Furthermore, we report the fidelity of dynamic assembly in tPNA as a function of position along the peptide backbone. Finally, we present theoretical studies that explore the level of fidelity that can be expected for an oligomer having a given hybridization affinity in dynamic templated reactions and provide guidance for the future development of sequence self-editing polymers and materials. As our results demonstrate, the use of molecular conjugates of constitutionally static and dynamic polymers establishes a new methodology for expediting the characterization of the complex chemical equilibria that underlie the assembly of dynamic informational polymers., 2018年01月09日, Biochemistry, 57 (1), 160 - 172, doi;pubmed;scopus;scopus_citedby

  • パラジウム触媒による酸素を用いた炭化水素類の末端選択的な酸化反応の開発を目指して

    浦康之

    © 2018 Society of Synthetic Organic Chemistry. All rights reserved. Selective oxyfunctionalization at the terminal carbon of alkenes, alkanes and other hydrocarbons using molecular oxygen can become industrially and/or synthetically useful, environmental load- reducing synthetic methods for oxygen-containing organic compounds such as primary alcohols, aldehydes, and their derivatives. In this paper, we report the palladium-catalyzed synthesis of aldehydes and terminal acetals by anti-Markovnikov oxidation of vinylarenes using molecular oxygen (and also p-benzoquinone), and oxygenation of a benzyl ligand in palladium complexes. The former catalytic aerobic anti-Markovnikov oxidation reactions were efficiently promoted in the presence of a catalytic amount of electron-deficient cyclic alkenes such as maleimides and p- quinones, which would coordinate to palladium to accelerate the reaction as well as to stabilize in- situ formed Pd(0) species and suppress the deactivation. The latter oxygenation was remarkably accelerated by the addition of anion sources or Bronsted acids, affording oxygenated compounds such as benzaldehyde, benzyl hydroperoxide, and benzyl alcohol. The oxygenation with anion sources proceeds in a radical chain mechanism, while the oxygenation with Brønsted acids proceeds in a non-radical chain mechanism. Especially, the oxygenation with acids would be promising because catalytic oxygenation of toluenes and other hydrocarbons can be developed by combining the oxygenation step with a deprotonative C-H bond activation step., 2018年, 有機合成化学協会誌, 76 (12), 1291 - 1300, doi;scopus;scopus_citedby

  • Ruthenacyclopentanes as Intermediates in the Regio- and Stereoselective Linear Codimerization of N-Vinylamides with Electron-Deficient Alkenes

    Hiroko Fukuzawa; Nozomi Aoyagi; Ruriko Sato; Yasutaka Kataoka; Yasuyuki Ura

    © 2017 American Chemical Society. Tricarbonylruthenacyclopentanes were successfully synthesized by in situ reduction of RuCl3 with Zn-Cu/CO in the presence of N-vinylacetamides and electron-deficient alkenes such as ethyl acrylate, dimethyl fumarate, and dimethyl maleate. X-ray crystallography of the ruthenacyclopentanes revealed that the three carbonyl ligands occupied coordination sites facially, and the ruthenacycle moiety was stabilized by coordination with the acetamido oxygen atom. When the ruthenacyclopentanes in toluene or DMA were heated to 130 °C for 24 h, linear codimers of the alkenes were formed in moderate to good yield. Both the ruthenacyclopentane and the RuCl3/Zn-Cu/alcohol system showed catalytic activity for the linear codimerization of alkenes, affording the codimers in good yield. The results of stoichiometric and catalytic reactions revealed that the codimerization can proceed via ruthenacyclopentane intermediates., 2017年10月23日, Organometallics, 36 (20), 3931 - 3939, doi;web_of_science;scopus;scopus_citedby

    © 2017 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim A copper hydride cluster [Cu8(μ-H)6(μ-dppm)5](PF6)2 (dppm=bis(diphenylphosphino)methane) was prepared from reaction of [CuH(PPh3)]6 with dppm in the presence of [Cu(CH3CN)4]PF6 and exhibited fluxional behaviors in solution where the hydrides and the phosphines are scrambling around the trans-bicapped octahedral Cu8 framework. The Cu8H6 complex showed facile reactivity with CO2 (1 atm, RT) to afford a tricopper complex, [Cu3(μ-H)(μ-O2CH)(μ-dppm)3]PF6, which could be developed to unprecedented hydrosilylation of CO2 catalyzed by multinuclear CuH species under mild conditions., 2017年07月18日, Chemistry - A European Journal, 23 (40), 9457 - 9461, doi;web_of_science;pubmed;scopus;scopus_citedby

  • Palladium-Catalyzed Aerobic Synthesis of Terminal Acetals from Vinylarenes Assisted by π-Acceptor Ligands

    Satoko Matsumura; Ruriko Sato; Sonoe Nakaoka; Wakana Yokotani; Yuka Murakami; Yasutaka Kataoka; Yasuyuki Ura

    © 2017 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim Terminal acetals were synthesized from various vinylarenes and 1,2- or 1,3-diols using a simple PdCl2(MeCN)2/methoxy-p-benzoquinone (MeOBQ)/CuCl catalyst system and 1 atm of O2 under mild reaction conditions by the anti-Markovnikov nucleophilic attack of an oxygen nucleophile on the coordinated vinylarenes. Cyclic α,β-unsaturated carbonyl compounds such as MeOBQ and N-phenylmaleimide were especially effective as additives to afford higher yields of the desired terminal acetals. Kinetic experiments indicated that MeOBQ operates as a π-acceptor ligand for Pd to accelerate the reaction and that the dissociation of a chloride ion from Pd precedes the rate-determining step., 2017年03月08日, ChemCatChem, 9 (5), 751 - 757, doi;web_of_science;scopus;scopus_citedby

  • Linear Triplatinum Tetrahydride Complex Supported by Triphosphine Ligands, [Pt?(μ-H)?(H)?(μ-dpmp)?](BF?)? (dpmp = bis(diphenylphosphinomethyl)phenyl phosphine)

    © 2017 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim By treating [Pt6(µ-H)(H)2(µ-dpmp)4]BH4 [4, dpmp = bis(diphenylphosphinomethyl)phenylphosphine] with an excess amount of HBF4 in N,N-dimethylformamide (DMF), a triplatinum tetrahydride complex, [Pt3(µ-H)2(H)2(µ-dpmp)2](BF4)2 (5), was obtained in 51 % yield and was characterized by IR, UV/Vis, 1H NMR, and 31P{1H} NMR spectroscopy in addition to ESI mass spectrometry, X-ray crystallography, and DFT calculations. Complex 5 is composed of linear trinuclear platinum centers supported by two dpmp ligands, {Pt3(µ-dpmp)2}6+, which accommodate two terminal and two bridging hydrides in a HPtHPtHPtH zigzag structure. The hydride positions were determined by DFT optimization with B3LYP/GD3BJ functionals. Variable-temperature 1H{31P} NMR spectroscopy in [D7]DMF revealed that the bridging hydrides exhibit fluxional behavior and migrate along the Pt3 chain by switching the bridging site, whereas the terminal hydrides are not exchanged with the bridging ones. The present results suggest that the divalent linear triplatinum unit of {Pt3(µ-dpmp)2}2+ (Pt3II), which is a building block to construct [Pt6(µ-H)(H)2(µ-dpmp)4]+ (4, Pt3IIPt3II), formally acts as a four-electron source to result in [Pt3(µ-H)2(H)2(µ-dpmp)2]2+ (5, Pt3VI) through protonation., 2017年, Eur.

    © The Royal Society of Chemistry 2016. Reactions of a tetraphosphine, meso-bis{[(diphenylphosphinomethyl)phenyl]phosphino}propane (dpmppp), with [IrCl(cod)]2 and CO (1 atm) or isocyanide (RNC) in the presence of NH4PF6 at 80-100°C in dichloromethane/acetonitrile/acetone and/or methanol mixed solvents afforded asymmetric diiridium(ii) complexes, [Ir2(H)(Cl)(μ-(dpmppp-H)-κP4C)(CO)3]PF6 (1) and [Ir2(H)(μ-(dpmppp-H)-κP4C)(RNC)4)]-(PF6)2 (R = 2,6-xylyl (2), 2,4,6-mesityl (3); dpmppp-H = {PPh(o-C6H4)CH2P(Ph)(CH2)3P(Ph)CH2PPh2}-). A similar reaction with tBuNC resulted in the formation of a mononuclear IrIII complex of [Ir(H)(dpmppp-κP3)(tBuNC)2](PF6)2 (4). Complexes 1-3 were characterized by ESI mass spectrometry, 1H and 31P NMR spectroscopy and X-ray diffraction analyses. They were found to consist of cis/trans-P,P asymmetric IrII-IrII bonded dinuclear structures derived from oxidative addition of an ortho C-H bond of dpmppp (Ir-Ir = 2.8044(2) Å (1), 2.8569(2) Å (2), and 2.8524(5) Å (3)), resulting in a [IrPCCIr] intermetallic cyclometal-bridge and a terminal hydride. DFT calculations indicated the presence of Ir-Ir, Ir-H, and Ir-Cortho covalent bonds. Initial stages of the reactions with CO and XylNC at room temperature were investigated by 31P{1H} NMR spectroscopy and found to contain a symmetrical IrI dinuclear unit with dpmppp that was readily transformed into 1 and 2 upon heating. The IrI2 intermediate with XylNC, [Ir2(XylNC)4(μ-dpmppp)](PF6)2 (6), was isolated and characterized by X-ray crystallography and DFT calculations as an electron-deficient 32e- IrI2 species involving a IrI→IrI dative bond (2.7989(5) Å). The reaction pathways from 6 to 2 were investigated by DFT calculations. The present study suggested that a novel oxidative addition of an ortho C-H bond proceeded on the cis/trans-P,P asymmetric diiridium(i) scaffold supported by the tetraphosphine, dpmppp, which was assumed to be facilitated by dimetal cooperation with switching Ir→Ir dative interactions., 2016年, Dalton Transactions, 45 (11), 4747 - 4761, doi;web_of_science;scopus;scopus_citedby

    © 2016 Royal Society of Chemistry. A cationic SNS-benzylpalladium complex was reacted with O2 under several conditions, affording oxygenated compounds derived from the benzyl ligand. The addition of n-Bu4NX remarkably accelerated the oxygenation, furnishing benzaldehyde as a main organic product and dinuclear complexes; in contrast, HX also promoted the oxygenation, but mainly produced benzyl hydroperoxide and mononuclear complexes., 2016年, Dalton Transactions, 45 (41), 16112 - 16116, doi;web_of_science;scopus;scopus_citedby

  • Facile insertion of carbon dioxide into Cu2(μ-H) dinuclear units supported by tetraphosphine ligands

    Kanako Nakamae; Bunsho Kure; Takayuki Nakajima; Yasuyuki Ura; Tomoaki Tanase

    © 2014 Wiley-VCH Verlag GmbH & Co. KGaA. Reactions of meso-bis[(diphenylphosphinomethyl) phenylphosphino]methane (dpmppm) with CuI species in the presence of NaBH4 afforded di- and tetranuclear copper hydride complexes, [Cu2(μ-H)(μ-dpmppm)2]X (1) and [Cu4(μ-H)2(μ4-H)(μ-dpmppm)2]X (2) (X = BF4, PF6). Complex 1 undergoes facile insertion of CO2 (1 atm) at room temperature, leading to a formate-bridged dicopper complex [Cu2(μ-HCOO)(dpmppm)2]X (3). The experimental and DFT theoretical studies clearly demonstrate that CO2 insertion into the Cu2(μ-H) unit occurred with the flexible dicopper platform. Complex 2 also undergoes CO2 insertion to give a formate-bridged complex, [Cu4(μ-HCOO)3 (dpmppm)2]X, during which the square Cu4 framework opened up to a linear tetranuclear chain., 2014年09月09日, Chemistry - An Asian Journal, 9 (11), 3106 - 3110, doi;web_of_science;scopus;scopus_citedby

  • Tiara-like octanuclear palladium(II) and platinum(II) thiolates and their inclusion complexes with dihalo- or iodoalkanes

    Yukari Yamashina; Yasutaka Kataoka; Yasuyuki Ura

    A tiara-like octanuclear palladium thiolate complex, [Pd(μ-SCH 2CO2Me)2]8, that has a toroidal structure was synthesized via reactions of either PdCl2 with methyl thioglycolate/N,N-diisopropylethylamine (DIEA) (conventional method) or [PdCl2(MeCN)2] with m-C6H4(CMe 2SCH2CO2Me)2 (alternative method). In the latter method, the tiara-like complex formed via the corresponding SCS-pincer complex and/or 1:1 PdCl2 and ligand complexes. With respect to the platinum analogues, the alternative method efficiently produced the tiara-like octanuclear complex [Pt(μ-SCH2CO 2Me)2]8 in high purity. Small molecules, such as CH2Cl2, ClCH2CH2Cl, CH 2Br2, and CH3I, were accommodated in the inner voids of the tiara rings to form 1:1 inclusion complexes. These complexes are stabilized not only by weak CH⋯X hydrogen bonds (X = Cl or Br) between the methylene protons of four or eight axially positioned methoxycarbonylmethyl groups on the tiara rings and the halogen atoms of the guest molecules but also by weak coordination of the halogen atoms to the transition-metal atoms. © 2014 American Chemical Society., 2014年04月, Inorganic Chemistry, 53 (7), 3558 - 3567, doi;web_of_science;pubmed;scopus;scopus_citedby

  • Fluxional interconversion of divalent palladium complexes having NSNSN ligands between flexible SNS and rigid NNN-coordinated structures

    Yumi Kawada; Yasutaka Kataoka; Yasuyuki Ura

    Mono- and dicationic divalent palladium complexes having 2,6-bis(N-heteroarylsulfanylmethyl)pyridine ligands (NSNSN ligands) were synthesized and characterized. The NSNSN ligands were fixed in a rac-SNS tridentate coordination mode in the solid state, while the equilibria among meso-SNS, rac-SNS, and NNN isomers were observed in solution. The equilibrium between the SNS and NNN isomers could be modulated by temperature, as well as by the steric and electronic factors of the NSNSN and monodentate ligands. Lowering the temperature tended to make NNN isomers more predominant compared with SNS isomers. On the other hand, the steric demand between the ligands in the complexes shifted the equilibrium from NNN to SNS isomers. Introduction of pyridyl groups instead of pyrimidyl groups as N-heteroarenes also shifted the equilibrium to SNS isomers. DFT calculation indicated rapid ring inversion of the metallacycle moieties and relatively slow S-inversion in the SNS isomers, a result that was in good agreement with the experimentally observed dynamic behaviors. Both the experimental and theoretical results revealed that the SNS isomers had flexible structures in solution, whereas the NNN isomers were rigid and less dynamic. The mechanistic pathways for interconversion between SNS and NNN isomers were also calculated. Such calculations indicated that a pathway featuring a relatively unstable, distorted ax-SNN intermediate was plausible. The intermediate had an N-heteroarene on the coordinated sulfur atom at an axial position. © 2013 The Royal Society of Chemistry., 2013年11月07日, Dalton Transactions, 42 (41), 14844 - 14855, doi;web_of_science;pubmed;scopus;scopus_citedby

    A palladium-catalyzed reaction of vinylarenes, allyl ethers, and 1,5-dienes with pinacol proceeded via a selective anti-Markovnikov nucleophilic attack to afford corresponding terminal acetals as major products.

  • Ruthenium-catalyzed reduction of N-alkoxy- and N-hydroxyamides

    Hiroko Fukuzawa; Yasuyuki Ura; Yasutaka Kataoka

    A ruthenium-catalyzed reduction of N-alkoxy- and N-hydroxyamides was found to afford corresponding amides in good to high yields. A simple RuCl 3/Zn-Cu/alcohol system, without the addition of any other ligands, exhibited a high catalytic activity, and therefore the present reaction does not require a stoichiometric amount of metals or metal complexes as reductants. When β-substituted-α,β-unsaturated N-methoxyamides were employed as substrates, concurrent hydrogenation of the olefin moiety proceeded slowly with deprotection of the methoxy group. In the reduction of N-hydroxyamides, the alcoholic solvent was found to function as a hydrogen donor. © 2011 Elsevier B.V.

  • Self-assembling sequence-adaptive peptide nucleic acids

    Yasuyuki Ura; John M. Beierle; Luke J. Leman; Leslie E. Orgel; M. Reza Ghadiri

    Several classes of nucleic acid analogs have been reported, but no synthetic informational polymer has yet proven responsive to selection pressures under enzyme-free conditions. Here, we introduce an oligomer family that efficiently self-assembles by means of reversible covalent anchoring of nucleobase recognition units onto simple oligo-dipeptide backbones [thioester peptide nucleic acids (tPNAs)] and undergoes dynamic sequence modification in response to changing templates in solution. The oligomers specifically self-pair with complementary tPNA strands and cross-pair with RNA and DNA in Watson-Crick fashion. Thus, tPNA combines base-pairing interactions with the side-chain functionalities of typical peptides and proteins. These characteristics might prove advantageous for the design or selection of catalytic constructs or biomaterials that are capable of dynamic sequence repair and adaptation., 2009年07月03日, Science, 325 (5936), 73 - 77, doi;web_of_science;pubmed;scopus;scopus_citedby

  • Dynamic polythioesters via ring-opening polymerization of 1,4-thiazine-2,5-diones

    Yasuyuki Ura; Mohammad Al-Sayah; Javier Montenegro; John M. Beierle; Luke J. Leman; M. Reza Ghadiri

    We describe the preparation and characterization of polythioesters composed of alternating α-amino acid and α-thioglycolic acid residues that undergo dynamic constitutional exchange under mild conditions. The polymers are assembled via reversible ring-opening polymerizations of 1,4-thiazine-2,5-diones and related monomers in solution-phase conditions that do not require the use of transition metal catalysts. Because 1,4-thiazine-2,5-diones can be derived in part from α-amino acids, a variety of side chain functionalized monomers in optically pure forms could readily be accessed. In addition, the resulting polythioesters have the potential for intra- and inter-chain hydrogen bonding, which is known to impart materials properties to other previously studied polyamides. The studies reported here could be useful in advancing a new class of biodegradable polymers and furthermore suggest that dynamic constitutional exchange could be exploited to modify many known synthetic and natural polythioesters. © 2009 The Royal Society of Chemistry., 2009年, Organic and Biomolecular Chemistry, 7 (14), 2878 - 2884, doi;web_of_science;pubmed;scopus;scopus_citedby

  • Ruthenium complex-catalyzed highly selective co-oligomerization of alkenes

    Yasuyuki Ura; Hiroshi Tsujita; Take Aki Mitsudo; Teruyuki Kondo

    Ruthenium complex-catalyzed reactions often require highly qualified tuning of reaction conditions with substrates to attain high yield and selectivity of the products. In this review, our strategies for achieving characteristic ruthenium complex-catalyzed co-oligomerization of different alkenes are disclosed: 1) The codimerization of 2-norbornenes with acrylic compounds by new ruthenium catalyst systems of RuCl3(tpy)/Zn [tpy = 2,2′:6′,2″-terpyridine] or [RuCl2(η 6-C 6H6)]2/Zn in alcohols, 2) A novel synthesis of 2-alkylidenetetrahydrofurans from dihydrofurans and acrylates by zerovalent ruthenium catalysts, such as Ru(η4-cod)(η6-cot) [cod = 1,5-cyclooctadiene, cot = 1,3,5-cyclooctatriene] and Ru(η 6-cot)(η2-dmfm)2 [dmfm = dimethyl fumarate], 3) Regio- and stereoselective synthesis of enamides by Ru(η6-cot) (η2-dmfm)2-catalyzed codimerization of N-vinylamides with alkenes, and 4) Unusual head-to-head dimerization of styrenes and linear codimerization of styrenes with ethylene by Ru(η6-cot) (η2-dmfm)2 catalyst in the presence of primary alcohols., 2007年12月20日, Bulletin of the Korean Chemical Society, 28 (12), 2139 - 2152, web_of_science;doi;scopus;scopus_citedby

    A novel zerovalent ruthenium complex with a π-acidic ligand, Ru(η6-cyclooctatriene)(η2-dimethyl fumarate) 2 (1), was prepared from Ru(η4-cyclooctadiene) (η6-cyclooctatriene) [Ru(cod)(cot)]. Complex 1 or Ru(cod)(cot) catalyzes various new carbon-carbon bond-forming reactions that include the [2 + 2] cycloaddition of alkenes and alkynes via ruthenacycles, the creation of a new hydrocarbon, pentacyclo[6.6.0.02,6.03,13.0 10,14]tetradeca-4,11-diene [PCTD], by dimerization of 2,5-norbornadiene via C-C bond cleavage, and the codimerization of alkynes and/or alkenes. Complex 1 was shown to be an excellent mother complex for various zerovalent ruthenium complexes. Complex 1 reacts with amines, phosphines or water to give new zerovalent ruthenium complexes with the ligands. The resulting aqua complexes have a water ligand with an oxygen atom that is a chiral center, i.e., ruthenium complexes with a 'chiral water' ligand were prepared and fully characterized., 2007年, Proceedings of the Japan Academy Series B: Physical and Biological Sciences, 83 (3), 65 - 76, web_of_science;doi;scopus;scopus_citedby

  • Formation of divalent ruthenacycles via oxidative cyclization of 1,3,5-cyclooctatriene with maleic anhydride or maleimides: An intermediate for the transition metal-mediated [6 + 2] cycloaddition of 1,3,5-trienes and alkenes

    Yasuyuki Ura; Taka Aki Utsumi; Hiroshi Tsujita; Kenji Wada; Teruyuki Kondo; Take Aki Mitsudo

    Reactions of a zerovalent ruthenium complex, Ru(η4-cod) (η6-cot) (3; cod = 1,5-cyclooctadiene, cot = 1,3,5- cyclooctatriene), with maleic anhydride or maleimides under mild reaction conditions afforded a series of novel divalent ruthenacycles 4 with an η5-cyclooctadienyl moiety via oxidative cyclization between the carbon-carbon double bonds of cot and the electron-deficient alkene. The solid-state structure clearly showed a newly constructed ruthenacycle skeleton, which was formed in a trans manner. Complex 4 was further reacted with H 2 and HCl to give hydrogenated and protonated succinimides with a C8-ring, respectively. When 4 was heated in toluene, a [6 + 2] cycloadduct of cot and a maleimide was obtained via reductive elimination, which shows that a ruthenium-mediated stepwise [6 + 2] cycloaddition was achieved. The addition of PPh3 to complex 4d promoted the reductive elimination, while bidentate phosphines such as 1,2-bis(diphenylphosphino)ethane did not give the cycloadduct and stable ruthenacycles 11 were formed instead. Reactions of 4 with CO gave novel tricarbonyl ruthenacycles 12 along with dissociation of the cod ligand, where neither reductive elimination nor CO insertion took place. The results of a theoretical study were consistent with the idea that the energy barriers for reductive elimination from ruthenacycles bearing cod or monophosphine ligands were lower than those from a ruthenacycle bearing a diphosphine ligand. The formation of 12 was found to be more energetically favorable than reductive elimination. © 2006 American Chemical Society., 2006年06月05日, Organometallics, 25 (12), 2934 - 2942, doi;web_of_science;scopus;scopus_citedby

    The reaction of Ru(η6-cot)(dmfm)2 (1; cot = 1,3,5-cyclooctatriene, dmfm = dimethyl fumarate) with water and dppe derivatives (dppe = 1,2-bis(diphenylphosphino)ethane) having two or four methoxy groups at the ortho positions of the phenyl rings, (S,S)-DIPAMP or o-MeO-dppe, afforded the unique binuclear Ru(II) aqua complexes 4a,b, where two oxaruthenacycles are combined and hold a water molecule by coordination and hydrogen bonding, as revealed by X-ray crystallography. Although complex 4b has a binuclear form in the solid state, disintegration occurred in solution to give the mononuclear aqua complex 4b′. Complex 4b was further treated with ammonia, resulting in the formation of the mononuclear Ru(II) ammonia complex 5 via ligand displacement with water. The water oxygen atom and ammonia nitrogen atom in these complexes can be regarded as chiral centers in the solid state, since they have four different groups, distinguished by coordination to ruthenium and nonequivalent hydrogen bondings. © 2006 American Chemical Society., 2006年05月08日, Organometallics, 25 (10), 2547 - 2552, doi;web_of_science;scopus;scopus_citedby

  • Chemistry of Ru(η6-1,3,5-cyclooctatriene) (η2-dimethyl fumarate)2

    The chemistry of a novel zerovalent Ru complex, Ru(η6-cot) (η2-dmfm)2 (1) (cot = 1,3,5-cyclooctatriene; dmfm = dimethyl fumarate), is reviewed with a focus on its reactivity toward phosphines, amines, and H2O, as well as arenes and p-quinones. A variety of novel zerovalent Ru complexes were synthesized from Ru(η6-cot)(η2-dmfm)2 (1), and it was shown that the complexes preferably bear both elecrron-donating and -accepting ligands simultaneously to exhibit thermodynamic stability. The first isolable zerovalent Ru aqua complexes were successfully prepared, and in these complexes, the generation of a chiral center on the O atom of the coordinated H 2O was disclosed. In addition, the characteristic catalytic activity of 1 in organic synthesis was considered by reviewing recently developed novel reactions: (i) dimerization of 2,5-norbornadiene to pentacyclo[6.6.0.0 2,6.03,13.010,14]tetradeca-4,11-diene (PCTD), (ii) intramolecular hydroamination of aminoalkynes to cyclic imines, (iii) formal [4 + 2] cycloaddition of alkynes with dmfm to trans-4-cyclohexene-1,2- dicarboxylates, and (iv) co-dimerization of dihydrofurans with α,β-unsaturated esters to 2-alkylidenetetrahydrofurans. The products obtained here are expected to be used as novel functional organic monomers. © 2006 The Japan Chemical Journal Forum and Wiley Periodicals, Inc., 2006年, Chemical Record, 6 (3), 107 - 116, doi;web_of_science;pubmed;scopus;scopus_citedby

    Enantiopure organoruthenium aqua complexes, Ru(dppe)(dmfm) 2(H2O) (1) [dmfm = dimethyl fumarate] and Ru(QUINAP)(dmfm)2(H2O) (2) [QUINAP = 1-(2- diphenylphosphino-1-naphthyl)isoquinoline], were prepared and the absolute structures were determined by X-ray crystallography. In the crystals of these complexes, the water molecule is captured in the chiral coordination environment assisted by two different hydrogen bonds; that is, a chiral center is generated on the coordinated oxygen of water. The behavior of the coordinated water in 1 and 2 was monitored by variable-temperature 1HNMR measurement. At lower than -60 to -70 °C, the nonequivalency of the geminal protons in the coordinated water molecule was observed even in solution. On the basis of the VT NMR data and DFT study, the behavior of the coordinated water was discussed. Complex 1 reacts with ammonia to give Ru(dppe)(dmfm)2(NH3) (4), which is the first example of the isolated mononuclear Ru(0) ammonia complex. Complex 4 was reversibly converted into 1 by the reaction with water. © 2005 American Chemical Society., 2005年11月07日, Organometallics, 24 (23), 5724 - 5731, doi;web_of_science;scopus;scopus_citedby

  • Ruthenium-catalyzed [2 + 2+ 2] cycloaddition of three different alkynes

    Yasuyuki Ura; Yoshitaka Sato; Hiroshi Tsujita; Teruyuki Kondo; Misako Imachi; Take Aki Mitsudo

    A chemoselective [2 + 2 + 2] cycloaddition of an internal alkyne, a terminal alkyne and dimethyl acetylenedicarboxylate was efficiently catalyzed by Cp*RuCl(cod) to give trisubstituted o-phthalates in good yield. It is critical to control the molar ratio of the three substrates to achieve high chemoselectivity, and regioselectivity of the products is sensitively influenced by the bulkiness of substituents on the internal alkyne. © 2005 Elsevier B.V.

  • Ruthenium-complex-catalyzed regio- and stereoselective linear codimerization of 2-norbornenes with acrylic compounds

    Yasuyuki Ura; Hiroshi Tsujita; Kenji Wada; Teruyuki Kondo; Take Aki Mitsudo

    A linear codimerization of 2-norbornenes with acrylic compounds such as acrylates and an acrylamide proceeded efficiently by ruthenium catalyst systems, RuCl3(tpy)/Zn (tpy = 2,2′:6′,2″-terpyridine) or [RuCl2(C6H6)]2/Zn in a primary or secondary alcoholic solvent, to afford the corresponding exo-trans-2- norbornylacrylates as major products regio- and stereoselectively along with a small amount of cis isomers. The reaction of 2,5-norbornadiene with methyl acrylate also gave the linear exo-trans codimer, which was effectively catalyzed by the addition of triarylphosphines to the RuCl3(tpy)/Zn catalyst system. © 2005 American Chemical Society., 2005年08月19日, Journal of Organic Chemistry, 70 (17), 6623 - 6628, doi;web_of_science;scopus;scopus_citedby

    Teruyuki Kondo; Fumiaki Tsunawaki; Yasuyuki Ura; Kazuo Sadaoka; Tomomichi Iwasa; Kenji Wada; Take Aki Mitsudo

    Reaction of Ru(η6-cot)(dmfm)2 (1) [cot = 1,3,5-cyclooctatriene, dmfin = dimethyl fumarate] with phenol was investigated. At 110°C, a novel ruthenium(II) phenolate complex, Ru(η5- C6H5O)(η5-C8H11) (2), was obtained by the reaction of 1 with phenol in an isolated yield of 52% (74% by NMR). When the reaction was carried out at 130°C, further dehydrogenative ring-closure in an η5-cyclooctadienyl ligand occurred to give Ru(η5-C6H5O)(η5-C 8H9) (3) in an isolated yield of 61% (76% by NMR). For both complexes, the η5-oxocyclohexadienyl bonding mode of a phenoxo ligand was clearly shown by X-ray crystallography and DFT calculation. Complex 2 was smoothly transformed into complex 3 in the presence of dmfm at 130°C for 3 h. Selective O-methylation of an η5- oxocyclohexadienyl ligand in complex 3 proceeded with methyl p-toluenesulfonate to give a novel cationic ruthenium(II) complex, [Ru(η6-C 6H5OMe)(η5-C8H 9)]+OTs- (4), in an isolated yield of 74%. © 2005 American Chemical Society., 2005年02月28日, Organometallics, 24 (5), 905 - 910, doi;web_of_science;scopus;scopus_citedby

  • Ru(η6-1,3,5-cyclooctatriene)(η2-dimethyl fumarate)2: A novel, versatile zerovalent ruthenium complex with electron-deficient olefinic ligands

    Take Aki Mitsudo; Yasuyuki Ura; Teruyuki Kondo

    The reactions of a novel zerovalent ruthenium complex, Ru(η 6-1,3,5-cyclooctatriene)(η2-dimethyl fumarate) 2, which has high catalytic activity for a carbon-carbon bond forming reaction, with various ligands such as phosphines, amines, arenes and p-quinones were reviewed. The reactivity of a novel zerovalent ruthenium complex, Ru(η6-cot)(η2-dmfm)2 (cot = 1,3,5-cyclooctatriene, dmfm, =dimethyl fumarate), which is readily prepared from Ru(η4-cod)(η6-cot) (cod = 1,5-cyclooctadiene) and dmfm was examined. The reaction with monodentate phosphine or amine ligands gave Ru(η6-cot)(dmfm)(L) (L = ligand) via dissociation of dmfm. Among bidentate phosphines, dppm (dppm = bis(diphenylphosphino)methane) reacted to give Ru(η4-cot)(dmfm)(dppm) along with releasing a dmfm ligand. In the case of dppe (dppe = 1,2-bis(diphenylphosphino)ethane), two types of complexes were obtained depending on the reaction conditions, Ru(dmfm)(dppe)2 and an alkyl alkenyl complex; in the formation of the latter complex, sp2 C-H bond activation of dmfm occurred. Ru(η4-cot)(dmfm)(N'down curve sign'N) and Ru(dmfm)2 (N'down curve sign'N'down curve sign'N) were formed by reacting with bidentate and tridentate nitrogen ligands. The reactions with arenes gave π-coordinated complexes, Ru(η6-arene)(dmfm)2. p-Quinones and a p-biqunone reacted to give Ru(η6-cot)(p-quinone) and {Ru(η6-cot)}2(p-biquinone), respectively, along with the dissociation of two dmfm ligands. It was found that low-valent ruthenium complexes preferably bear both electron-donating and accepting ligands simultaneously to be thermodynamically stable. © 2004 Elsevier B.V.

    Formal [4 + 2] cycloaddition of alkynes with electron-deficient alkenes, which affords 3,6-dialkyl-4-cyclohexene-1,2-dicarboxylates, was achieved using Ru(η6-1,3,5-cyclooctatriene) (η2-dimethyl fumarate)2 as a catalyst. The reaction mechanism consists of two steps, isomerization of an alkyne to conjugated dienes and successive Diels-Alder reaction of the generated dienes with an electron-deficient alkene. © 2004 Elsevier B.V.

    A highly chemoselective intermolecular [2+2+2] cycloaddition of 2eq. of terminal alkynes with dimethyl acetylenedicarboxylate, which enables the straightforward synthesis of dialkylated o-phthalates, was successfully accomplished using a ruthenium catalyst, Cp*RuCl(cod) (Cp*: pentamethylcyclopentadienyl, cod: 1,5-cyclooctadiene). The co- cyclotrimerisation of alkynes and acetylenedicarboxylates usually affords 1:2 adducts (1,2,3,4-benzenetetracarboxylates), however, in the present reaction 2: 1 adducts (o-phthalates) are the major products unprecedentedly. © 2003 Elsevier B.V.

    Ru(η6-cot)(dmfm)2 (1; cot = 1,3,5-cyclooctatriene, dmfm = dimethyl fumarate), which is easily derived from Ru(1-2:5-6-η-cod)(η6-cot) (cod = 1,5-cyclooctadiene), reacts with an excess amount of pyridine to give a novel ruthenium(0) complex, Ru(dmfm)2(pyridine)3 (4). Complex 1 reacts with tridentate pyridyl ligands (N-N′-N) such as 2,2′:6′,2″-terpyridine (terpy), 2,6-bis(imino)pyridyl ligands, and 2,6-bis[(4S)-(-)-isopropyl-2-oxazolin-2-yl]pyridine (i-Pr-Pybox) to give novel ruthenium(0) complexes, Ru(dmfm)2(N-N′-N). The products are mixtures of two isomers, respectively, one of which is different from the other by the coordinating enantioface of a dmfm ligand.

    Ru(η6-cot)(η2-dmfm)2 (1; cot = 1,3,5-cyclooctatriene, dmfm = dimethyl fumarate) reacted with p-quinones to give novel p-quinone-coordinated ruthenium(0) complexes, Ru(η6-cot)(p-quinone) (2), in good to high yields via the replacement of two dimethyl fumarates by p-quinones. The reaction of 1 with p-biquinone gave a novel bimetallic zerovalent complex {Ru(η6-cot)}2(p-biquinone) (3), in which p-biquinone coordinates to two isolated "Ru(cot)" moieties with a unique mode and the two Ru(cot) groups are located at endo positions. Complexes 2 and 3 have either p-quinone or p-biquinone as π-acceptor ligands.

  • Palladium-Catalyzed Anti-Markovnikov Oxidation of Aromatic and Aliphatic Alkenes to Terminal Acetals and Aldehydes

    Yasuyuki Ura

    AbstractCatalytic anti-Markovnikov (AM) oxidation of terminal alkenes can provide terminally oxyfunctionalized organic compounds. This short review mainly summarizes our recent progress on the Pd-catalyzed AM oxidations of aromatic and aliphatic terminal alkenes to give terminal acetals (oxidative acetalization) and aldehydes (Wacker-type oxidation), along with related reports. These reactions demonstrate the efficacy of the PdCl2(MeCN)2/CuCl/electron-deficient cyclic alkenes/O2 catalytic system. Notably, electron-deficient cyclic alkenes such as p-benzoquinones (BQs) and maleimides are key additives that facilitate nucleophilic attack of oxygen nucleophiles on coordinated terminal alkenes and enhance the AM selectivity. BQs also function to oxidize Pd(0) depending on the reaction conditions. Several other factors that improve the AM selectivity, such as the steric demand of the nucleo­philes, slow substrate addition, and halogen-directing groups, are also discussed. 1 Introduction 2 Anti-Markovnikov Oxidation of Aromatic Alkenes to Terminal Acetals­ 3 Anti-Markovnikov Oxidation of Aromatic Alkenes to Aldehydes 4 Anti-Markovnikov Oxidation of Aliphatic Alkenes to Terminal Acetals­ 5 Anti-Markovnikov Oxidation of Aliphatic Alkenes to Aldehydes 6 Conclusion, 2021年03月, Synthesis, 53 (05), 848 - 860, doi;url

KGaA, Weinheim Copper hydride compounds have attracted interest in diverse fields as base metallic material in place of rare and noble metals, which have widely been utilized in hydrogenation catalysts, hydrogen storage, and electrochemical materials. Since the first report on the synthesis of copper hydride complex [Cu6H6(PPh3)6] in 1971, copper hydride reagents have been utilized in a variety of organic transformation. While well-characterized copper hydride complexes have been long limited to a few examples, recently several research groups have reported the synthesis of phosphine-stabilized copper hydride complexes with various metal-frameworks and unique reactivity. Here we review recent progress on the synthesis and structures of copper hydride complexes supported by phosphine ligands, including di-, tri-, and tetraphosphines, and also describe their reactivity with CO2., 2020年06月23日, European Journal of Inorganic Chemistry, 2020 (23), 2211 - 2226, doi;scopus;scopus_citedby;url
