摘要：

2,4,5-Trisubstituted imidazoles have been synthesized by treatment of benzil with aldehydes and ammonium acetate in water under reflux in the presence of p-dodecylbenzenesulfonic acid as catalyst. The same reaction using an additional amine affords 1,2,4,5-tetrasubstituted imidazoles. The products are formed in high yields within 4 h under eco-friendly conditions.
