Abstract
Two polysiloxanes with pendant fullerene moieties and their platinum or rho dium complexes have been prepared from C-60 via amination with omega-deceny lamine, followed by hydrosilylation with triethoxysilane and immobilization on fumed silica or by hydrosilylation with methyldichlorosilane and polyco ndensation with polydimethylsiloxanol, and then by reacting them with potas sium chloroplatinite or rhodium chloride in acetone respectively under argo n atmosphere. It was found that the four noble metal complexes are effectiv e catalysts for the hydrosilylation of olefins with triethoxysilane. The re gioselectivity of platinum complexes for styrene increases remarkably by in troducing C-60 moiety. Factors influencing catalytic activity and the mecha nism have been investigated.
