An Efficient and Green Synthesis of Imidazoles Using Natural Organic Acids as Promoter under Solvent-Free Condition

Abstract

An efficient and eco-friendly synthesis of imidazoles, promoted by naturally occurring acids, via condensation of benzil, aldehyde and ammonium acetate using conventional and microwave heating under solvent-free condition is described. Reactions under microwave irradiation are faster and gave slightly higher yields against conventional heating.
