Abstract

A set of novel yttrium complexes that display unprecedented coordination geometries for the ligands S-H₃L^Me, R-H₃L^iPr, and H₃L^Me is developed. These complexes are promising catalysts for the ring-opening polymerization of lactide. The demonstration of readily manipulated ligand effects on polymerization reactivity in these discrete, well-characterized complexes represents an important step in the development of highly selective lanthanide catalysts for the controlled synthesis of polylactide acid and other polyesters.
