用新型的双磺酸型离子液体为催化剂,以乙酰乙酸乙酯和间苯二酚为原料,通过Pechmann反应在无溶剂条件下,用微波促进方式合成了香豆素,与传统方法相比,剔除了溶剂的使用,反应时间短,收率高,是一种环境友好的合成方法。%To explore an easily-controled,environmentally-benign synthetic method of coumarin.Coumarin was synthesized from phenols and ethyl acetoacetates by the Pechmann reaction under microwave irradiation and solvent-free conditions.Compared with traditional reaction,present method under microwave and ionic liquid avoids using of organic solvent,shorten the reaction period and obtain a good yield.
