Cationic zinc complexes: a new class of catalyst for living lactide polymerization at ambient temperature

Author affiliations

Abstract

Cationic zinc complexes of a bis(phosphinimine) pincer ligand have been prepared. Methylzinc and zinclactate complexes have been structurally characterized, and the latter is the first cationic metal complex to promote coordination–insertion polymerization of lactide at ambient temperature. This novel catalyst system is remarkably active and also exhibits living character. A detailed investigation of the kinetics and mechanism of the polymerization process has been undertaken.
