| Abstract: | The paper reported that the aldol reaction of aromatic aldehyde and aromatic ketone at room temperature could be efficiently promoted by the use of mixed solvent of ionic liquid 3-butyl-1-methylimidazolium p-toluenesulfonate（p-CH3C6H4SO3]） and water.The results show the ionic liquid/aqueous mixture could efficiently accelerate the reaction of the aldol condensation and the yield could reach up to 81% at room temperature in the presence of 25% volume ionic liquid.The present protocol may offer several advantages including mild reaction conditions,simple work-up procedure,short reaction time and high yields. |
