From Molecule to Material: How Support Changes Heterobimetallic Catalysts in Lactide Polymerization.
Ontology highlight
ABSTRACT: Sustainable production of polylactide demands catalysts that are both recoverable and capable of delivering precise molar mass and stereocontrol. A series of heterobimetallic complexes [(THF)NaFe(OtBu)3]2, [(THF)2KFe(OtBu)3]2, [KZn(OtBu)3]2, [(THF)KCu(OtBu)3]∞ and [(THF)KCo(OtBu)3]2 was evaluated as precursors for heterogeneous catalysts by grafting onto dehydroxylated silica. All complexes demonstrated activity in the ring-opening polymerization of lactide. Notably, the silica-supported [(THF)KFe(OtBu)2]/SiO2-700 and [(THF)NaFe(OtBu)2]/SiO2-700 systems exhibited high efficiency, promising recyclability, a
