  甲硅烷基化的三芳基膦配体对铑催化的氢化硅烷化的影响

  摘要：

  合成了一系列甲硅烷基化的三芳基膦。研究了RhCl 3 /甲硅烷基化的三芳基膦配合物催化的苯乙烯与三乙氧基硅烷的硅氢化反应。RhCl 3 /苯基双（4-三甲基甲硅烷基苯基）膦和RhCl 3 / tris（4-三甲基甲硅烷基苯基）膦的配合物显示出更高的活性以及更大的β-加合物选择性，没有得到不饱和产物。结果表明，甲硅烷基部分对催化过程具有重大影响。版权所有©2016 John Wiley＆Sons，Ltd.

• Hydrosilylation catalysed by a rhodium complex in a supercritical CO2/ionic liquid system

  日期：——

  The hydrosilylation of alkenes in a supercritical CO2 (scCO2)/ionic liquid (IL) system was investigated. Rh(PPh3)3Cl exhibited excellent catalytic activity and selectivity. KOtBu was used as an additive, and no hydrogenation by-product (alkane) was detected in the scCO2/IL system. During hydrosilylation in the scCO2/IL system, the reactants were possibly transferred into the IL phase by scCO2, in which the catalyst was dissolved. The products can be flushed with scCO2 after the reaction and the catalyst/IL system reused.

  在超临界二氧化碳（scCO2）/离子液体（IL）体系中研究了烯烃的氢硅化反应。Rh(PPh3)3Cl表现出优异的催化活性和选择性。KOtBu作为添加剂，在scCO2/IL体系中未检测到氢化副产物（烷烃）。在scCO2/IL体系中进行氢硅化反应时，反应物可能通过scCO2转移到IL相中，催化剂在该相中溶解。反应后，产物可通过scCO2冲洗，催化剂/IL体系可重复使用。

  functionalized triarylphosphane ligands are characterized by a very high catalytic effectiveness for the hydrosilylation of alkene. Among these catalysts tested, RhCl3/diphenyl(2‐(trimethylsilyl)phenyl)phosphane (8a) exhibited excellent catalytic properties. Using this silicon‐containing phosphane ligand for the rhodium‐catalyzed hydrosilylation of styrene, both higher conversion of alkene and higher β‐adduct

  合成了一系列三芳基膦（1a，2a，3a，4a，5a，6a，7a，8a，9a，10a，11a）。（2-溴苯基）二苯基膦（1a）的X射线晶体结构分析明确证实了官能化膦的组成。RhCl 3催化苯乙烯与三乙氧基硅烷的硅氢化反应研究了三芳基膦。与经典的威尔金森氏催化剂相比，具有官能化三芳基膦配体的铑配合物的特征是对烯烃的氢化硅烷化具有很高的催化效率。在这些测试过的催化剂中，RhCl 3 /二苯基（2-（三甲基甲硅烷基）苯基）膦（8a）表现出优异的催化性能。使用这种含硅的膦配体进行铑的苯乙烯氢化硅烷化反应，与威尔金森催化剂相比，烯烃的转化率更高，β-加合物的选择性更高。版权所有©2014 John Wiley＆Sons，Ltd.

  Rhodium complexes bearing N-heterocyclic carbene (NHC) ligands were prepared from bis(η4-1,5-cyclooctadiene) dichlorodirhodium and 1-alkyl-3-methylimidazolium-2-carboxylate, and the catalytic properties of rhodium complexes prepared in the hydrosilylation of alkenes in ionic liquid media were investigated. It was found that both the catalytic activity and selectivity of the rhodium complexes bearing

• Graphite oxide-supported Karstedt catalyst for the hydrosilylation of olefins with triethoxysilane
  作者：Fuyuan Rao、Shengjun Deng、Chao Chen、Ning Zhang

  DOI：10.1016/j.catcom.2013.10.043

  日期：2014.2

  A graphite oxide-supported Karstedt heterogeneous catalyst was synthesized from vinyltriethoxysilane via immobilization on graphite oxide, followed by reacting with chloroplatinic acid. The samples were characterized by FT-IR, TGA, ICP-AES, XRD and TEM techniques. The catalyst was active for hydrosilylation of olefins with triethoxysilane and showed good recoverability without significant loss in activity and selectivity within successive runs.
