Pf. Fang et al., Synthesis and catalytic behavior of polysiloxane-supported fullerene platinum or rhodium complexes, CHIN J POLY, 17(5), 1999, pp. 441-446
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.
