Hydrosilylation of n-alkenes and allyl chloride over platinum supported on styrene–divinylbenzene copolymer

Catalytic performance of styrene–divinylbenzene copolymer-supported platinum catalyst of high crosslinking degree and high surface area was studied in reactions of hydrosilylation of allyl chloride, 1-octene and 1-butene. The catalyst has shown considerably greater stability of catalytic activity than classical active carbon-supported catalyst. In experiments on repeated use of catalysts, the decrease in catalytic activity for hydrosilylation of liquid double bond-containing compounds proceeding in the presence of the copolymer-supported and carbon-supported platinum was considerably smaller in the case of the former catalyst. Bimetallic Pt–Cu catalyst on polymeric support appeared to be considerably less active than monometallic catalyst.
