Alkenyl, aryl or allylic selenides smoothly couple with Grignard reagents in the presence of Ni(II)-phosphine complexes as catalysts to afford the corresponding unsaturated compounds in good yields.The reactivity order of coupling reaction with BuMgBr catalyzed by NiCl2 was found to be PhSeMe >> PhCl > PhSMe by the competitive reactions.
