An indium complex supported by a ferrocene-derived Schiff base ligand has unprecedented activity toward ε-caprolactone, δ-valerolactone, and β-butyrolactone ring-opening polymerizations. l-Lactide, d,l-lactide, and trimethylene carbonate polymerizations also showed moderate to high activity.

Schiff Base Metal Complexes

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.
