A NEW TYPE OF CROWN FUNCTIONALIZED POLYSILOXANE AND ITS PLATINUM COMPLEX

A new type of crown functionalized polysiloxane, in which the crown moieties were incorporated into main chain, and its platinum complex were synthesized. The polysiloxane was synthesized from 3, 16-dihydroxy-1- thia - 5, 8, 11, 14- tetraoxacycloheptadecane via etheritication with ω-chloroundecene,...

Zusammenfassung:A new type of crown functionalized polysiloxane, in which the crown moieties were incorporated into main chain, and its platinum complex were synthesized. The polysiloxane was synthesized from 3, 16-dihydroxy-1- thia - 5, 8, 11, 14- tetraoxacycloheptadecane via etheritication with ω-chloroundecene, followed by hydrosilylation with triethoxysilane, cohydrolysis with D4, sequentially. Treating the polysiloxane with potassium cholroplatinite, the title complex was obtained. It was found that the platinum complex exhibited high catalytic activity in the hydrosilylation of olefins with triethoxysilane.
