Indium Complex

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.

Cyclic Esters

A dimeric yttrium phenoxide complex can be oxidized in a stepwise fashion to access three oxidation states. The three states show different activity in the ring opening polymerization of cyclic esters and epoxides.
