ABSTRACT:
Catalyst compounds comprising at least one transition metal in an oxidation state of 0 to 1, and at least one monodentate or bidentate water-soluble phosphine, well suited for the hydrocyanation of ethylenically unsaturated compounds, 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 monodentate or bidentate water-soluble phosphine, advantageously at least one phosphine having the following formulae (I) and/or (II):
