摘要: 超声辐射下,对查尔酮与含活泼亚甲基的化合物诸如丙二酸二乙酯、硝基甲烷、乙酰乙酸乙酯、环己酮等,在KF/basic Al2O3催化下的Michael 反应进行了研究,该法具有反应时间短、产率高、操作简单、催化剂可以重复使用的优点.

关键词: 超声波, 查尔酮, Michael 加成, KF/basic Al2O3

Abstract: The Michael reaction of chalcones as acceptors with several active methylene compounds such as diethyl malonate, nitromethane,ethyl acetoacetate and cyclohexone et al as donors catalyzed by KF/basic Al2O3 under ultrasound irradiation proceed very efficiently and furnish higher yield of adducts.

Key words: ultrasound, chalcones, Michael addition, KF/basic Al2O3
