【摘要】 N,N—双(β—乙硫乙基)γ—(三乙氧硅基)丙胺单独或与十二烷基三乙氧基硅烷或与苯丙基三乙氧基硅烷共同以气相法二氧化硅固定化,再与氯亚铂酸钾反应,合成三种含双(β—乙硫乙基)胺基的高分子配体及其铂配合物。它们都是烯烃与三乙氧基硅烷的硅氢加成反应的有效催化剂。更多还原

【Abstract】 Three new polysesquisiloxane-bound platinum complexes were synthesized via hydrolysis of N,N-di(β-ethylmercaptoethyl)ν- (triethoxysilyl) propylamine or cohydrolysis of the monomer with dodecyltriethoxysilane or with phenylpropyltriethoxysilane and immobilization on fumed silica,followed by reacting with potassium chloroplatinite in acetone under Ar atmosphere.The platinum complexes exhibited high catalytic activity for the hydrosilylation of olefins by triethoxysilane. The effects of temperature and the amount of complex on the catalytic activity, as well as the recovery and reusability of the catalysts were investigated.更多还原
