successfully applied in the enantioselective Reformatskyreaction and addition of diethylzinc to N-(diphenylphosphinoyl)imine, respectively. The influence of the substituents on C-3 position and the amino moiety on the enantioselectivity has been carefully investigated. In the best cases, ligand 1b exhibited good selectivity for the enantioselective Reformatskyreaction in 86% ee and ligand 12d provided excellent
