Inside Back Cover: Synthesis of Diverse Polycarbonates by Organocatalytic Copolymerization of CO 2 and Epoxides: From High Pressure and Temperature to Ambient Conditions (Angew. Chem. Int. Ed. 4/2022)

Abstract

The synergetic binary phosphazene/triethylborane (TEB) system is highly active and selective towards the ring-opening alternating copolymerization of CO2 with different epoxides to prepare diverse CO2-based polycarbonates (CO2-PCs). In their Research Article (e202111197), Shaofeng Liu, Zhibo Li, and co-workers report that this metal-free organocatalyst can efficiently copolymerize CO2 with cyclohexene oxide under ambient conditions (1 atm pressure and room temperature), which is an environmentally friendly and more carbon-balanced way toward CO2 utilization.
