Abstract:

2-Amino-5-(2-phenyl-1,2,3-triazol-4-yl)-1,3,4-thiodiazole has been prepared by reaction of 2-phenyl-1,2,3-triazole-4-carboxylic acid with aminothiourea in the presence of phosphorus oxychloride. Then a series of novel N-[5-(2-phenyl-1,2,3-triazol-4-yl)-1,3,4-thiodiazol-2-yl]-N′-aroylthioureas have been synthesized by reaction of compound 1 with aroyl isothiocyanates by means of ultrasonic radiation method and ordinary method. The structures of these compounds were confirmed by elemental analysis, IR and 1H NMR spectroscopy.

Key words: ultrasonic radiation,aroyl thiourea,thiodiazole,phenyltriazole
