ABSTRACT
The application of ultrasound in organic synthesis has gained considerable momentum as a consequence, several organic transformations were effected using ultrasound. Sonochemistry is gaining significant importance in organic synthesis based on laboratory results and the availability of scale-up systems. This chapter discusses name reactions that have been carried out under sonochemical conditions. Those are aldol condensation, Baylis-Hillman Reaction, benzoin condensation, Biginelli reaction, Blaise reaction, Cannizzaro reaction, Claisen-Schmidtcondensation, Diels-Alder reaction, Heck reaction, Henry reaction, Knoevenagel condensation, Mannich reaction, Pinacol coupling reaction, Reformatsky reaction, Sonogashira coupling, Strecker synthesis, Suzuki reaction and Ullmann reaction. Deng et al. established that it is feasible to carry out a large number of conventional reactions in the synthesis and fictionalization of carbohydrates under ultrasound irradiation with better yields and reduced reaction times. Sonochemical switching is a unique feature of sonochemistry, which differentiates this technique from other methods enhancing chemical reactions.
