Abstract Michael addition of chalcone with active methylene compound such as diethyl malonate, nitromethane and ethyl acetoacetate catalyzed by potassiumhydroxide in anhydrous ethanol results Michael adducts in 75–98% yield under ultrasound irradiation in 25–90 min.
of several active methylene compounds to chal-cone, catalyzed in interfacialsolid-liquidconditions is described.The mecha -nism of the process is analyzed using the Michael addition of diethyl malonate to chalcone as the reaction test. Several microcrystalline bariumhydroxide ca-talysts are tested.The nature of the solid catalyst active sites taking part in the process is discussed. The presence
