Herein, azole-anion-based aprotic ionic liquids (ILs) were synthesized by the deprotonation of weak proton donors (e.g., 2-methylimidazole, 4-methylimidazole, and 2,4-dimethylimidazole) with tetrabutylphosphonium hydroxide, [Bu4P][OH]. These ILs, such as [Bu4P][2-MIm], could activate atm. CO2 through the formation of carbamates. The resultant carbamate intermediates could further react with various types of substrate, including propargylic alcs., 2-aminobenzonitriles, ortho-phenylenediamines, and 2-aminothiophenol, thereby producing α-alkylidene cyclic carbonates, quinazoline-2,4(1H,3H)-diones, benzimidazolones, and benzothiazoline, resp., in moderate-to-good yields. The transformation of CO2 at atm. pressure was achieved, and this method is expected to open up new routes for the synthesis of various oxygen-containing heterocyclic compounds under metal-free conditions.
