• 2,4,5-Triaryl-1H-imidazole
• Boric acid
• Aqueous media
• Ultrasound irradiation

Boric acid (BO(3)H(3)) is an inexpensive, efficient and mild catalyst For the synthesis of 2,4,5-triaryl-1H-imidazoles in excellent yields from the one-pot three-component condensation of benzil/benzoin, an aldehydes and ammonium acetate in aqueous media under ultrasound at room temperature. The remarkable advantages offered by this method are green catalyst, mild reaction conditions, simple procedures, much faster reactions and excellent yield of products.
