Sodium Imino-quinolates with Cubic and Hexagonal Prismatic Motifs:Synthesis, Characterization and Their Catalytic Behavior Toward the ROP of rac-Lactide
Biodegradable polylactide (PLA) has been the focus of much attention in recent years due to its numerous applications in packaging, agricultural materials, drug delivery, medical devices, and so on.1 Subsequently, various complex catalysts have been extensively investigated and well reviewed recently2,3.In this work.a series of sodium 2-arylimino-8-quinolates, differing in both the nature of the aryl and quinolate substituents, was prepared and characterized.Their X-ray structures reveal multimetallic assemblies adopting a variety of structural cores all based on Na-O repeat units: cubic and tetrametallic or hexagonal prismatic and hexametallic.In the presence of BnOH, all complexes exhibit good activities towards the ring-opening polymerization (ROP) of rac-lactide, affording amorphous polylactides with broad molecular weight distributions.Furthermore, the substituent variation within the ligand frame affects the catalytic activities of the ROP with the least sterically hindered system.
