Abstract The crystalline complexes L2Zn (1), L3Al (2), L′2Zn (3) and L'AlMe2 (4) were synthesized from the reactions of the corresponding chiral ligands (S) N-(2-pyrrolylmethylene)-1-phenylethylamine (HL) or (S) N-(2-pyrrolylmethyl)-1-phenylethanamine (HL′)… Click to show full abstract
Abstract The crystalline complexes L2Zn (1), L3Al (2), L′2Zn (3) and L'AlMe2 (4) were synthesized from the reactions of the corresponding chiral ligands (S) N-(2-pyrrolylmethylene)-1-phenylethylamine (HL) or (S) N-(2-pyrrolylmethyl)-1-phenylethanamine (HL′) and diethylzinc or trimethylaluminum, respectively. Complexes 1–4 were well characterized by 1H NMR, 13C NMR spectroscopy, elemental analyses and single crystal X-ray crystallography. Furthermore, the catalytic activities toward ring-opening polymerization (ROP) of rac-lactide have been investigated and all of the complexes can be used as initiators to give the isotactic-rich polylactides.
