CO2/epoxide copolymerization catalyzed by Zinc complexes containing alkyl and aryl substituted β-ketoiminate ligands

초록

Even though aryl-substituted β-diketiminato zinc complexes have been prepared and investigated for the copolymerization of CO2/epoxide, studies with alkyl and aryl substituted β-diketiminato zinc complexes are rare. Recent efficient syntheses of alkyl and aryl substituted β-diketimines make it possible to investigate the electronic and steric effects on the catalytic behaviors of new Zn complexes for CO2/epoxide copolymerization. Preparation and characterization of these new ligands and complexes and catalytic behaviors for CO2/epoxide copolymerization will be presented.
