In this work, the combined use of ultrasonic energy and molecular sieves was investigated for synthesis of 3-(5-substituted-1,3,4-thiadiazol-2-ylimino)indolin-2-one derivatives 5(a–j). The equimolar quantities of 5-substituted-1,3,4-thiadiazol-2-amine and isatin were sonicated in the presence of activated molecular sieves 3 Å at a temperature of 50 °C and(More)
