Abstract
A rapid, efficient, and simple ultrasonic-assisted protocol is reported for the synthesis of benzo thiazol-selenazol skeletons from the one-pot reactions of acyl iso (seleno or thio) cyanate, benzothiazole and various terminal alkynes, in the vicinity of a copper catalyst, without the help of additional ligands under ultrasonic conditions for 45 min with good efficiency. The role of ultrasound in this reaction is to reduce the time, increase the efficiency of product preparation, and make the work-up easier. The use of simple and available raw materials, mild copper catalytic reaction conditions, easy purification with the help of a solvent, and finally, the synthesis of 10 new compounds from the benzo thiazol-selenazol family are notable features of this protocol.
