摘要
研究1-甲基-3-丁基咪唑对甲苯磺酸盐([bmim][p-CH3C6H4SO3])离子液体/水体系促进室温下碱催化芳醛与芳酮Aldol缩合反应.实验结果显示,在室温下,离子液体体积分数为25%,离子液体/水体系对苯甲醛与苯乙酮间Aldol缩合反应具有更明显的加速作用,缩合产物收率达到81%以上;该方法具有条件温和、操作简单、反应时间短、产率高等特点.
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.
