摘要： 高分子负载膦铂配合物是一类很好的烯烃硅氢加成催化剂[1],但迄今未见有关螯合型双膦铂配位负载催化剂的报道。1983年,Micholska报道了胺膦双齿配体铑配合物的合成与催化性能。最近,我们合成了气相法二氧化硅负载的聚-4-氧杂-6,7-双二苯膦庚基硅氧烷铭配合物, 并证实是烯烃硅氢加成的良好催化剂[3]。

关键词: 双齿型膦铂配合物, 硅氢化反应, 二氧化硅负载催化剂

Abstract: 4-Oxa-6,7-dichloroheptyltrimethoxysilane was synthesized from 4-oxa-6,7-dichlorohept-1-ene via hydrosilylation with trimethoxysilane in the presence of tetrakis (triphenylphos-phine)platinum complex as catalyst. The chlorine-containing silicon monomer was subjectedto phosphatization with potassium diphenylphosphide, immobilized on the fumed silica andreacted with potassium chloroplatinite in acetone, giving the title complex. The bidentate phosphine platinum complex was found to exhibit high catalytic activityfor the hydrosilylation of decene, dodecene, ω-chloroundecene, phenyl allyl ether,allyl ben-zene and glycidyl allyl ether with triethoxysilane. The yields of the adducts were 72 to 94%.The title complex could be recovered and reused several runs without loss of activity.

Key words: bidentate phosphine platinum complex, hydrosilylation, silica-supported catalyst
