(-Hydeoxy ketones are important organic compounds, especially benzoins have important application in chemistry and pharmacy. In this paper, an improved synthesis of benzoin in mild conditions was described and benzoin condensation reactions of aldehydes catalyzed by 1-methyl-3-benzylimidazolium chloride give the corresponding products with moderate to high yields.

Key words: benzoin, ionic liquid, synthesis, catalyze, ultrasonic radiation
