Abstract

N-Heterocyclic Olefin (NHO) with high electronegativity at the terminal carbon atom was found to show a strong tendency for CO2 sequestration, affording a CO2 adduct (NHO– CO2). X-ray single crystal analysis revealed the bent geometry of the binding CO2 in the NHO–CO2 adducts with an O–C–O angle of 127.7–129.9°, dependent on the substitute groups of N-heterocyclic ring. The length of the Ccarboxylate–CNHO bond is in the range ...
