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/basicAl2 O3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 . 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 Al_2O_3 under ultrasound irradiation proceed very efficiently and furnish higher yield of adducts.
