Solvent-free synthesis of tetrasubstituted imidazoles on silica gel/NaHSO4 support

An efficient synthesis of various tetrasubstituted imidazoles using silica gel-supported sodium bisulfate as a catalytic support by four-component condensation of benzil or benzoin, aldehydes, amines, and ammonium acetate under microwave irradiation or classical heating conditions is described.
