Fume silica-bound poly-4,7-dithianonylsesquisiloxane platinum complex was prepared from 4,7-dithianonyltrimethoxysilane and fume silica via hydrolysis, followed by treatment with potassium chloroplatinite in acetone under Ar atmosphere. The complex exhibited a high catalytic actvity on the hydrosilylation of olefins with triethoxysilane. Even at a molar ratio of olefin to complex of 10⁵, the hydrosilylation reaction took place smoothly with the turnover number more than 80,000.
