Synthesis of a novel functional polymer immobilized platinum complex and its application in the catalytic hydrosilylation of 3,3,3-trifluoropropene with triethoxysilane

A novel polymer has been synthesized using 2-vinylpyridine as a functional monomer and allyl polyethylene glycol as a cross-linking agent, and platinum has been immobilized on this synthesized polymer. The resulting immobilized catalyst showed superior catalytic performance for the hydrosilylation of 3,3,3-trifluoropropene with triethoxysilane as compared to homogenous platinum catalyst, polystyrene-immobilized platinum or other hydrosilylation catalysts. The conversion of silane is about 100% and the maximum yield of β-adduct is 92.3% with slightly α-adduct. Furthermore, the catalyst showed sufficient stability that it could be reused three times without noticeable inactivation.
