摘要
新型的磺酸根功能化离子液体作为催化剂成功用于氧杂蒽二酮类衍生物的合成,在微波促进下,以水为溶剂合成了一系列的氧杂蒽二酮类衍生物,产物收率达到92-97%。其过程具有产品容易分离,催化剂可回收循环利用,不使用有机溶剂,反应时间短,操作简单,绿色环保等优点。
Novel SO3H-functionalized ionic liquids were successfully applied as catalysts for synthesis of xanthenediones under microwave irradiation in Aqueous. Various types of Xanthenes were provided in 92 ~97%yields using the catalytic system of [(HSO3-p)2im][CF3SO3]/H2 O. The products could be conveniently separated from the reaction mixture by filtration and the dissolved catalyst could be reused without any treatment, which of the separation process was performed in water without using any organic solvents. The method not only has the advantages of short time and simple operation, but also is environmentally friendly.
