In this thesis, we developed chiral proton N-O type ligands and employed them in the enantioselective addition of diethylzinc to N-diphenylphosphinoyl imines. The relationship between the structure of the ligands and the enantioselectivity was systematically studied. Furthermore, enantioselective butylation of N-diphenylphosphinoyl imines withBu〓Zn and enantioselective diphenylzinc addition to imine were also examined.
