  • Facile Regio- and Stereoselective Hydrometalation of Alkynes with a Combination of Carboxylic Acids and Group 10 Transition Metal Complexes: Selective Hydrogenation of Alkynes with Formic Acid
    作者:Ruwei Shen、Tieqiao Chen、Yalei Zhao、Renhua Qiu、Yongbo Zhou、Shuangfeng Yin、Xiangbo Wang、Midori Goto、Li-Biao Han

    日期:2011.10.26
    highly stereo- and regioselective hydrometalation of alkynes generating alkenylmetal complex is disclosed for the first time from a reaction of alkyne, carboxylic acid, and a zerovalent group 10 transition metal complex M(PEt(3))(4) (M = Ni, Pd, Pt). A mechanistic study showed that the hydrometalation does not proceed via the reaction of alkyne with a hydridometal generated by the protonation of a
    通过炔烃、羧酸和零价族 10 过渡金属络合物 M(PEt(3))(4) (M =镍、钯、铂)。一项机理研究表明,氢金属化不是通过炔烃与由羧酸与 Pt(PEt(3))(4) 质子化产生的氢化金属反应进行的,而是通过炔烃配位金属络合物与酸。这一发现阐明了长期以来提出的反应机制,该机制通过生成烯基钯中间体和随后在由 Brφnsted 酸和 Pd(0) 配合物的组合催化的各种反应中转化该配合物来进行。

    detected in photolyzed benzene solutions. Photolysis of 3 or 6 in the presence of 2,3-dimethyl-2-butene (TME) yields the chlorohydrin (2-chloro-2,3-dimethyl-3-butanol), 3-chloro-2,3-dimethyl-1-butene, and acetone, all expected products from HOCl trapping, but additional oxidation products are also observed. Photolysis of mixed chloro-bromo complex 7 with TME yields the bromohydrin (2-bromo-2,3-dimethyl-3-butanol)

    日期:2014.7.21
    Except for 2 (R = Ph, 4-trifluoromethylphenyl), all of the Pt(IV) complexes are photosensitive to UV light and undergo net halogen reductive elimination to give Pt(II) products, trans-Pt(PEt3)2(R)(X) (X = Cl, Br). Chlorine trapping experiments with alkenes indicate a reductive-elimination mechanism that does not involve molecular chlorine and is sensitive to steric effects at the Pt center. DFT calculations

    Triorganotin chlorides react with complexes of Pt0 to give products of insertion into the Sn–C rather than the Sn–Cl bond as reported previously. Products of the type cis-[PtR(PPh3)2(SnR′2X)](R = Ph, R′2X = Ph2Cl, MePhCl, Me2Cl, BrPh2, Ph2I, Ph2(OH), Ph2(ONO2), or Ph3) have been obtained from [Pt(C2H4)(PPh3)2] and SnPhR′2X, cis-[PtMe(PPh3)2(SnMe2Cl)] from [Pt(C2H4)(PPh3)2] and SnMe3Cl, and cis-[PtMe(PEt3)2(SnMe3)]

    日期:1982.7
    The phenyldicyanooxiranes, trans-2,3-dicyano-2,3-diphenyloxirane, 2,2-dicyano-3,3-diphenyloxirane, and 2,2-dicyano-3-phenyloxirane, are cleaved by platinum(O) tertiary phosphine complexes to afford zerovalent metal—olefin complexes and phosphine oxides. The π-olefin products were characterized by 1H and 31P 1H NMR spectroscopy and by an X-ray structure determination of Pt[trans-Ph(CN)CC(CN)Ph](PPh3)2·CH3OH
