## Abstract Ammonium metavanadate (NH~4~VO~3~) is an inexpensive, efficient and mild catalyst for the synthesis of 2,4,5‐triaryl‐1__H__‐imidazole from the one‐pot three‐component condensation of benzil/benzoin, an aldehyde and ammonium acetate in excellent yield. This method has the advantages of g
