ABSTRACT:
A process for purifying an impure vinylically-unsaturated organosilicon product compound prepared by reaction between a vinylically-unsaturated organosilicon precursor and a halogenated organic compound in the presence of a homogeneous zerovalent palladium catalyst complex, the catalyst complex including an organophosphine or organoarsine ligand, in the presence of a hydrogen halide acceptor in an essentially anhydrous diluent, comprising treating a mixture containing the impure vinylically-unsaturated organosilicon product compound with a peroxide for a time sufficient to oxidize organophosphine or organoarsine impurities present in a mixture being treated. The peroxide can be selected from aqueous hydrogen peroxide or organic peroxides. The thus-treated mixture can be further treated by chromatography over silica gel or alumina. In optional embodiments, chromatography over silica gel or alumina can precede treatment with the peroxide.
