Two polysiloxanes with pendant fullerene moieties and their platinum or rhodium complexes havebeen prepared from C60 via amination with ω-decenylamine

followed by hydrosilylation with triethoxysilaneand immobilization on fumed silica or by hydrosilylation with methyldichlorosilane and polycondensationwith polydimethylsiloxanol

and then by reacting them with potassium chloroplatinite or rhodium chloride inacetone respectively under argon atmosphere. It was found that the four noble metal complexes are effective catalysts for the hydrosilylation of olefins with triethoxysilane.The regioselectivity of platinum complexes for styrene increases remarkably by introducing C60 moiety.Factors influencing catalytic actalytic activity and the mechanism have been investigated.
