二氧化硅-聚硅氧烷负载富勒烯铂配合物的合成及其催化硅氢化性能

SYNTHESIS OF SILICA POLYSILOXANE SUPPORTED FULLERENE PLATINUM COMPLEX AND ITS CATALYTIC BEHAVIOR

富勒烯及其衍生物的催化性能的研究是当前的一个热点，并显示出良好的工业应用前景［１］．研究表明，富勒烯及其衍生物的金属配合物对氢化［２，３］，不对称偶联［４］，烯烃的聚合［５］等都有优异的催化性能．我们也发现Ｃ６０Ｐｔ（ＰＰｈ３）２和Ｃ６０Ｐｔｎ是高效...

Polysiloxane with fullerene moiety and its platinum complex have been prepared from C 60 (H 2NCH 2CH 2NH 2) 5 via reacting with γ glycidoxy propyl trimethoxy silane, followed by immobilization on fumed silica, then reacting with potassium chloroplatinite in acetone under argon atmosphere. The Pt complex is effective catalyst for hydrosilylation of olefin with triethoxysilane. It is found that the regioselectivity increases remarkably by introducing C 60 moiety. The influences of temperature, the amount of Pt complex used and the nature of olefin are investigated.
