Heterolepic β-Ketoiminate Zinc Phenoxide Complexes as Efficient Catalysts for the Ring Opening Polymerization of Lactide.

ABSTRACT: Zinc phenoxide complexes L¹ZnOAr 1-4 (L¹=Me₂NC₂H₄NC(Me)CHC(Me)O) and L²ZnOAr 5-8 (L²=Me₂NC₃H₆NC(Me)CHC(Me)O) with donor-functionalized β-ketoiminate ligands (L^1/2) and OAr substituents (Ar=Ph 1, 5; 2,6-Me₂-C₆H₃ 2, 6; 3,5-Me₂-C₆H₃ 3, 7; 4-Bu-C₆H₄ 4, 8) with tuneable electronic and steric properties were synthesized and characterized. 1-8 adopt binuclear structures in the solid state except for 5, while they are monomeric in CDCl₃ solution. 1-8 are act
