  铱催化乙烯基硅烷的对映选择性加氢

  摘要：

  我们已经筛选出了各种各样的手性N，P配体衍生的铱配合物，作为乙烯基硅烷不对称氢化的催化剂，这种转化方法缺乏通常适用的催化剂。从这项研究中出现了几种催化剂，它们能够对带有芳基，烷基，乙氧羰基或羟甲基取代基的三取代或二取代的末端C = C键的乙烯基硅烷进行高度对映选择性氢化。除三甲基甲硅烷基和二甲基（苯基）甲硅烷基衍生物外，三烷氧基甲硅烷基和硅杂环丁基取代的烯烃也用作底物。

  Pd-Catalyzed Coupling Reaction of Acetylenes, Iodotrimethylsilane, and Organozinc Reagents for the Stereoselective Synthesis of Vinylsilanes

  摘要：

  The reaction of terminal acetylenes with Me(3)SiI (1) and organozinc reagents in the presence of Pd(PPh(3))(4) results in addition of the trimethylsilyl group of 1 and an alkyl group of the organozinc reagent to the acetylenes. In all cases the trimethylsilyl group adds to the terminal carbon of the acetylenes. Both aromatic and aliphatic terminal acetylenes undergo the coupling reaction with high regio- and stereoselectivities. The yield and stereoselectivity are relatively sensitive to the nature of the organozinc reagent used. The reaction of phenylacetylene (2) using Bu(2)Zn gives the corresponding coupling product in high yield with high stereoselectivity (>98%). In contrast, the use of BuZnI results in 92% stereoselectivity. The stereoselectivity for the reaction using (Me(3)-SiCH2)(2)Zn is lower than those for Me(2)Zn, Et(2)Zn, and Bu(2)Zn. For organozinc reagents, alkylzinc works well while phenyl-, ethynyl-, and allylzinc do not. The reaction using Me(3)SiCl, Me(3)SiBr, Me(3)SiSPh, Me(3)SiSePh, and Me(3)SiOTf in place of 1 does not proceed. The reaction with Me(3)SiMe(2)-SiI and Me(3)SiMe(2)SiMe(2)SiI in place of 1 gives the corresponding vinyldisilane and -trisilane, respectively.

  iridium complexes derived from chiral N,P ligands as catalysts for the asymmetric hydrogenation of vinylsilanes, a transformation for which generally applicable catalysts were lacking. Several catalysts emerged from this study that enabled the highly enantioselective hydrogenation of a wide range of vinylsilanes with trisubstituted or disubstituted terminal C=C bonds bearing aryl, alkyl, ethoxycarbonyl,
