摘要：

Combined strength: Only the combination of aluminate complexes with their neutral Lewis acids allows the controlled regioregular ring-opening polymerization of industrially important propylene oxide. The chain propagation proceeds at both aluminium centers according to a novel mechanism (see scheme).
