Novel dichloro copper(II) and zinc(II) complexes of N1,N1-dimethyl-N2-(((1R)-6,6-dimethylbicyclo[3.1.1]hept-2-en-2-yl)methyl)ethane-1,2-diamine ligands were synthesised and characterised by X-ray diffraction. The alkoxide derivatives of the well characterized two complexes were assessed for ring opening polymerization (ROP) of rac-Lactide. The active catalyst species were generated by treating the complexes with 2 equivalent LiOCHMe2. Furthermore, the heterotactic polylactide with Pr up to 84 % can be obtained by using the initiator of the complex bearing N1,N1-dimethyl-N2-(((1R)-6,6-dimethylbicyclo[3.1.1]hept-2-en-2-yl)methyl)ethane-1,2-diamine in CH2Cl2 at room temperature. The stereoselectivity and molecular weight of the polymer was determined by 1H-NMR spectra, and GPC.
