An efficient and reusable catalyst, alkaline–modified Montmorillonite K10, has been developed and used in the Knoevenagel condensation. A series of condensation reactions based on ultrasound irradiation of different types of active methylene compou

The synthesis of 1,3-diaryl-2-propenones was carried out by using ultrasonic irradiation in the presence of silica-H2SO4, which was used as a catalyst in solvent-free conditions. The advantages of this process are the high yields (82–98%) it produc
