Abstract
A process for preparing a vinylically-unsaturated product compound comprises reacting a halogenated organic compound with a hydrolytically-stable, vinylically-unsaturated precursor compound in the presence of (a) a homogeneous zerovalent palladium catalyst complex, (b) an inorganic hydrogen halide acceptor and (c) a diluent, wherein the diluent is water or an aqueous solution containing up to 95% by volume of an organic solvent. The halogenated organic compound is selected from aryl halides, benzyl halides or vinylic halides. The hydrolytically-stable, vinylically-unsaturated precursor compound is selected from hydrocarbon compounds or compounds containing at least one of an oxygen atom, a nitrogen atom, a sulfur atom, a phosphorus atom or a combination thereof.
