摘要：(Chemical Equation Presented) 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. ? 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
