硅氢加成反应是把Si—H键加到不饱和烃上,生成含有饱和有机基团的硅烷的反应:此反应可由某些金属和金属卤化物催化.近年来,出现了一些对硅氢加成反应具有一定催化活性,而且容易回收使用的高分子催化剂.例如,Capka等人报道了带有二苯基膦、二甲胺基和氰基的交联聚苯乙烯,带有二苯基膦的交联聚丙烯酸与铑或铂的络合物. 我们在烟雾状二氧化硅(普通市售)表面上,进行了γ-氨丙基三乙氧基硅烷的水解缩合,制备了以二氧化硅为载体的聚-γ-氨丙基硅氧烷.然后使其和水合铂氯酸作用,得到聚-γ-氨丙基硅氧烷—铂络合物:
Hydrosilylation reactions are the addition of Si-H bonds to unsaturated hydrocarbons to form saturated organic-containing silanes: this reaction can be catalyzed by certain metals and metal halides. In recent years, For example, Capka et al. Reported cross-linked polystyrene with diphenylphosphine, dimethylamino and cyano groups with diphenyl Phosphine cross-linked polyacrylic acid with rhodium or platinum We carried out hydrolytic condensation of γ-aminopropyltriethoxysilane on the surface of fumed silica (generally marketed) to prepare bis Silica-supported poly-γ-aminopropylsiloxane, which was then reacted with hydrous platinum chloride to give a poly-γ-aminopropylsiloxane-platinum complex:
