摘要：

Despite recent advances regarding catalysts for CO2/epoxide copolymerization, the development of high-activity catalysts for alternating polymerization of CO2 and commodity epoxides, such as propylene oxide, remains a challenge. A new class of unsymmetrically substituted β-diiminate zinc complexes is reported that exhibits unprecedented activity for CO2/propylene oxide copolymerization. The polymers formed are of high molecular weight (Mn ≈ 35 kg/mol) and have narrow polydispersities (PDI ≈ 1.1), consistent with a living polymerization. Copyright © 2002 American Chemical Society.
