ABSTRACT A process of preparing a vinylically- -unsaturated product compound comprises reacting a halogenated organic compound with a vinylically- -unsaturated precursor compound in the presence of (a) a homogeneous zerovalent palladium catalyst complex, (b) a hydrogen halide acceptor and (c) a diluent, wherein the diluent is water or an aqueous solution containing up to 95 percent by volume of an organic solvent. The crude product from process for preparing an impure vinylically-unsaturated product compound by reacting a vinylically-unsaturated precursor compound 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, may be purified by treating the mixture containing the impure vinylically-unsaturated product 35,843A-F compound with a peroxide for a time sufficient to oxidize organophosphine or organoarsine impurities present in the mixture. 35,843A-F
