Imidazolium-2-carboxylates derived from N-heterocyclic carbenes (NHCs) and CO2 serve as efficient catalysts for CO2-carboxylation of tertiary aziridines bearing various substituents such as halogens, ether, olefin, ester, acetal, and nitro groups on the aziridine ring in 2-propanol, leading to 3-substituted-2-oxazolidones in good to excellent yields and with high selectivity. The NHC–CO2 adducts facilitate
