Abstract
Catalyst compounds comprising at least one transition metal having an oxidation number of 0 or 1 and at least one sulfonated phosphine are electrochemically synthesized, by electrolyzing an aqueous solution catholyte (contained in the cathode compartment of any suitable electrolytic cell) comprising at least one transition metal compound and at least one sulfonated phosphine.
