Anilido-imine zinc complexes: Efficient catalysts for ring-opening polymerization of L-lactide

Abstract

A series of anilido-imine zinc complexes ortho-C₆H₄(CH=NAr)(NAr)ZnEt[Ar=2,6-Me₂C₆H₃(2a); Ar=2,6-Et₂C₆H₃(2b)] was synthesized, characterized and used as catalysts for the ring-opening polymerization of L-lactide in the presence of benzyl alcohol. The effects of the structures of catalysts and reaction conditions on the reactivity were investigated. The polymerization of L-lactide initiated by each of these complexes was found to take place with a controlled manner.

Keywords
