Tetravalent metal complexes as a new family of catalysts for copolymerization of epoxides with carbon dioxide
New tetravalent metal complexes with a trianionic [ONNO]-tetradentate ligand and an ancillary chloride ligand were synthesized as catalysts for the copolymerization of epoxides with carbon dioxide (CO2). All of the titanium, zirconium, germaniu
