Electronic and Steric Effects on Catalysts for CO2/Epoxide Polymerization: Subtle Modifications Resulting in Superior Activities

CO2 is perhaps the most attractive carbon‐based feedstock owing to its abundance and low toxicity. Utilization of this contributor to global warming is a long‐standing goal. Reported here are new single‐site β‐diiminate zinc catalysts that exhibit unprecedented activities for CO2/epoxide polymerizat...

Description
Summary:CO2 is perhaps the most attractive carbon‐based feedstock owing to its abundance and low toxicity. Utilization of this contributor to global warming is a long‐standing goal. Reported here are new single‐site β‐diiminate zinc catalysts that exhibit unprecedented activities for CO2/epoxide polymerization (see scheme).
