SODIUM BISULFITE AS AN EFFICIENT AND ECONOMICAL CATALYST FOR ONE-POT SYNTHESIS OF 2, 4, 5 TRISUBTITUTED IMIDAZOLES FROM BENZIL, AMMONIUM ACETATE AND AROMATIC ALDEHYDES BY MICROWAVE IRRADIATION
A highly efficient method for the synthesis of substituted imidazoles from a multicomponent reaction of isatin derivatives with ammonium acetate and aromatic aldehydes under solvent-free conditions has been established.
α-Aminophosphonates were synthesised under solvent-free conditions on an acidic silica gel support using aromatic aldehydes, diethyl phosphite and anhydrous ammonium acetate as starting materials in moderate yields
