新型铂催化体系的开发及其在硅化学及硅橡胶中的应用

Development of a Platinum-based Catalytic System and its Application in Silicon Chemistry and Silicone Rubber

从分子设计角度出发,为炔烃的硅氢加成反应、新型环硅氧烷化合物和烯基功能化硅氧化合物的高效合成研制了一系列新型非均相/均相铂催化体系.该类催化剂较传统Karstedt催化剂具有更高的化学或立体选择性,为常规方法难以制备的硅烷提供了便捷高效的合成方法.制得的新型含烯基硅烷在硅橡胶的改性或作为硅橡胶助剂方面具有潜在用途.

A series of novel heterogeneous/homogeneous platinum catalytic systems have been developed by hydrosilylation of alkyne,the synthesis of a novel cyclosiloxanes and alkenyl funetionalized silyl enolates.The catalysts show a higher chemical or stereoselectivity than the conventional Karstedt catalysts,which pro-vides a convenient and efficient synthesis method for silane.The novel alkenyl-containing silane has potential applications in the modification of silicone rubber or as the additives of silicone rubber.
