Abstract: Acid hydrazide 1 when treated with aryl isothiocyanates gives the compounds 2. These compounds 2 on ultrasound irradiation in acidic medium give compounds 3 i.e. thiadiazoles and in basic medium gives compounds 4 i.e. triazoles. These compounds 2 on treatment with I2/KI and NaOH resulted in compounds 5 i.e. oxadiazoles. These compounds are synthesized by conventional method as well as ultra sound irradiation method.
