Abstract


Tannic acid (C76H52O46) has been found to be an efficient catalyst for one-pot synthesis of 2,4,5-triaryl substituted imidazoles by the reaction of an arylaldehyde, benzyl/benzoin and an ammonium acetate. The short reaction time and excellent yields making this protocol practical and economically attractive.

Keywords


ammonium acetate; benzyl; benzoin; imidazoles
