Fund Project: We are grateful to the Head of the Department of Chemistry, Dr. Babasaheb Ambedkar Marathwada University, Aurangabad-431004 (M.S.), India for providing the laboratory facility. We also thank Mr. S.S. Pawar, Department of Chemistry, Vinayakrao Patil Mahavidyalaya Vaijapur, Aurangabad-423701 (M.S.), India for moral encouragement during this research work.

2,4,5-Triarylimidazoles could be obtained in excellent yields by the one-pot three-component condensation of benzil/benzoin,aldehydes and ammonium acetate in the presence of catalytic amount of the inexpensive, readily available and non-toxic ceric (Ⅳ) ammonium nitrate (CAN) in aqueous media under ultrasound at room temperature. In this reaction the products were obtained in short reaction time and easy operation under mild conditions.
