摘要
从p-氯烯丙苯出发,通过相继地与三甲氧基硅烷进行硅氢加成、二苯膦钾膦化、气相法二氧化硅固载化,再与氯亚铂酸钾或三氯化铑反应,合成了聚γ-(p-二苯膦苯基)丙基硅氧烷铂、铑络合物。两者对烯烃与三乙氧基硅烷的硅氢加成反应具有良好的催化活性。
Poly-γ-(p-diphenyl phosphinophenyl)propyl siloxane platinum and rhodium complexeshave been synthesized from γ-(p-chlorophenyl)-propyltrimethoxysilane via phosphatizationwith potassium diphenylphosphide,immobilization and hydrolysis on fumed silica,followed byreaction with potassium chloroplatinite or rhodium chloride. They exhibited high catalyticactivity for the hydrosilylation of decene,dodecene, ω-chloroundecene, allyl benzene, phenylallyl ethe, and allyl glycidyl ether with triethoxysilane from 80 to 100℃ and could bereused several times without loss of activity.
