Abstract:Rice Husk was found to be an efficient catalyst for the green synthesis of biologically active2,4,5-Triaryl-1H-Imidazoles by the coupling of Benzil/Benzoin, aldehyde and ammonium acetate under ultrasound-irradiation at ambient temperature for appropriate time to furnish the desired product in good to excellent yield. The catalyst provides clean conversion; greater selectivity and easy workup make this protocol practical and economically attractive
