Abstract: Poly-γ-(p-diphenyl phosphinophenyl)propyl siloxane platinum and rhodium complexeshave been synthesized from γ-(p-chlorophenyl)-propyltrimethoxysilane via phosphatizationwith potassium diphenylphosphide,immobilization and hydrolysis on fumed silica,followed byreaction with potassium chloroplatinite or rhodium chloride. They exhibited high catalyticactivity for the hydrosilylation of decene,dodecene, ω-chloroundecene, allyl benzene, phenylallyl ethe, and allyl glycidyl ether with triethoxysilane from 80 to 100℃ and could bereused several times without loss of activity.

Key words: Supported catalyst, Triphenylphosphine platinum complex, Triphenylphosphine rhodium complex, Hydrosilylation
