A series of chiral organozinc complexes [(L-1)ZnEt](2) (1), [(L-2)ZnEt](2) (2) and [(L-3)ZnEt](2) (3) have been prepared by ethane elimination reaction between ZnEt2 and the corresponding chiral sulfonylamidoazetidine ligands, (1 ‘ S,2S,3S)-1-(1 ‘-Phenylethyl)-2-phenyl-3-isopropylsulfonamidoazetidine (HL1), (1 ‘ S,2S,3S)-1-(1 ‘-Phenylethyl)-2-phenyl-3-(p-tolylsulfonamido)azetidine (HL2), and (1 ‘ S,2S,3S)-1-(1 ‘-Phenylethyl)-2-phenyl-3-(m-tolylsulfona-mido)azetidine (HL3), respectively. These complexes were characterized by various spectroscopic methods and elemental analyses. The structures of 1 and 2 were further confirmed by single crystal X-ray diffraction. Complexes 1-3 are active catalysts for the ring-opening polymerization (ROP) of rac-lactide, leading to het-erotactic-rich polylactides under mild conditions.
