  铑N-杂环卡宾配合物的合成及其在离子液体介质中烯烃氢化硅烷化反应中的催化活性

  摘要：

  铑络合物轴承ñ -杂环卡宾（NHC）配体从双制备（η 4 -1,5-环辛二烯）dichlorodirhodium和1-烷基-3-甲基咪唑-2-羧酸乙酯，和铑配合物的催化性能在氢化硅烷化制备的研究了离子液体介质中烯烃的结构。已经发现，带有NHC配体的铑配合物的催化活性和选择性都受到咪唑鎓阳离子附着的替代物的影响。此外，在离子液体BMimPF 6中带有NHC配体的铑配合物可以重复使用而不会明显降低催化活性和选择性。

• 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。
• Graphite oxide-supported Karstedt catalyst for the hydrosilylation of olefins with triethoxysilane

  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.
