Facile syntheses of bimetallic ytterbium bisamides stabilized by a flexible bridged bis(phenolato) ligand and the high activity for the polymerization of l-lactide

Abstract

The “ate” and neutral bimetallic ytterbium bisamido complexes stabilized by a flexible bridged bis(phenolate) group are prepared, which exhibited high activity for the ring-opening polymerization of L-lactide.
