The first attempt to use chiral β-phosphino sulfoxides as chiralligands was successfully accomplished in a palladium-catalyzedasymmetricallylic alkylation and amination, providing extremely high enantioselectivity with chiral 2-(diphenyl-phosphino)phenyl 2-methoxy-1-naphthyl sulfoxide. The structure of the intermediary palladium complex chelated by the ligand was determined by the X-ray crystallographic
