The acidic ionic liquid, 1-(4-sulfonic acid) butyl-3-methylimidazolium hydrogen sulfate [MimC 4 SO 4 H]HSO 4 catalyzed two-component condensation reaction of phenacyl bromide and o -phenylenediamine to afford corresponding quinoxaline derivatives. The inexpensive and non-toxic ionic liquids can be reused several times without any perceptible loss of their activities.
酸性离子液体1-(4-磺酸)丁基-3-甲基咪唑硫酸氢盐[MimC 4 SO 4 H] HSO 4催化苯甲酰溴和邻苯二胺的两组分缩合反应,得到相应的喹喔啉衍生物。廉价且无毒的离子液体可以重复使用数次,而不会损失任何活性。
