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