This review describes the recent advances (from 2008 onwards) in the use of Schiff-base metal complexes as catalysts for the ring opening polymerization (ROP) of cyclic esters. The synthesis and structure of the metal complexes, as well as all aspects concerning the polymerization process and the characteristics of the polymers formed, will be discussed.

Recent Advances

Poly(α-hydroxy acids) are important biodegradable polymers with wide applications. Recently O-carboxyanhydrides (OCAs) have emerged as promising monomer equivalents of lactides to synthesize poly(α-hydroxy acids). We will highlight recent advances in controlled ring-opening polymerization of OCAs catalyzed by organocatalysts, enzymes, or organometallic complexes.1 Introduction2 Organocatalysts for O-Carboxyanhydride Polymerization2.1 Synthesis of O-Carboxyanhydride Monomers2.2 Ring-Opening Polymerization of O-Carboxyanhydrides Catalyzed by 4-Dimethylaminopyridine2.3 Epimerization in the Ring-Opening Polymerization of O-Carboxyanhydrides Catalyzed by the Pyridine Base2.4 N-Heterocyclic Carbenes for Ring-Opening Polymerization of O-Carboxyanhydrides3 Enzymes for O-Carboxyanhydride Polymerization4 Organometallic Catalysts for O-Carboxyanhydride Polymerization4.1 Early Efforts4.2 Ring-Opening Polymerization Catalyzed by Zn Complexes4.3 Photoredox Ring-Opening Polymerization Catalyzed by Zn/Ni Complexes5 Conclusion and Perspective
