High activity of an indium alkoxide complex toward ring opening polymerization of cyclic esters

Chem Commun (Camb). 2015 Jun 14;51(47):9643-6. doi: 10.1039/c5cc01312g.

Abstract

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