Efficient synthesis of quinazoline-2,4(1H,3H)-diones from CO₂ catalyzed by N-heterocyclic carbene at atmospheric pressure

Abstract

Under atmospheric pressure, quinazoline-2,4(1<italic>H</italic>,3<italic>H</italic>)-diones were obtained from the reaction of 2-aminobenzonitriles with carbon dioxide (0.1 MPa) with a catalytic amount of N-heterocyclic carbene in DMSO.
