Highly Heteroselective Ring‐Opening Polymerization of <i>rac</i>‐Lactide Initiated by Bis(phenolato)scandium Complexes

Abstract

Tactical response: High heterotactic stereocontrol was observed from the ring-opening polymerization of rac-lactide on using a series of bis(phenolato)scandium complexes (see scheme). This stereocontrol appears to involve a dynamic monomer-recognition process as a result of the interconversion of the configuration from Λ into Δ.
