Interfacial Frustrated Lewis Pairs Of Ceo2 Activate Co2 For Selective Tandem Transformation Of Olefins And Co2 Into Cyclic Carbonates
JOURNAL OF THE AMERICAN CHEMICAL SOCIETY(2019)
摘要
Effective activation of CO2 is a prerequisite for efficient utilization of CO2 in organic synthesis. Precisely controlling the interfacial events of solids shows potential for activation. Herein, defect-enriched CO2 with constructed interfacial frustrated Lewis pairs (FLPs, two adjacent Ce3+center dot center dot center dot O2-) effectively activates CO2 via the interactions between C/Lewis basic lattice O2- and the two O atoms in CO2/two adjacent Lewis acidic CO2 ions. Selective cyclic carbonate production from a catalytically tandem protocol of olefins and CO2 is used to demonstrate FLP-inspired CO2 activation.
