Abstract: Poly-4-oxa-6,7-bis(diphenylphosphino)heptyl siloxane rhodium complex was synthesized from 4-oxa-6,7-dichloroheptene-1 via hydrosilylation with trimethoxysilane in the presence of tetrakis (triphenylphosphine)platinum complex as the catalyst, phosphatization with potassium diphenylphos-phide, sequentially, followed by immobilization on fumed silica and then the reaction with rhodium chloride. It exhibited good catalytic activity for the hydrosilylation of olefins, such as decene, do-decene, w-chloroundecene, phenyl allyl ether, allyl benzene, allyl glycidyl ether, styrene, and methyl methacrylate, etc., with triethoxysilane at 90℃. Apossible structure pattern of this silicone-supported bidentate phosphine rhodium complex has been suggested.
