“…Generally, syntheses of 1,2,4-triazoles are accomplished by the condensation of 2-hydrazinoderivatives with carboxylic acids at elevated temperature, 14 1,3-dipolar cycloaddition reaction of aromatic nitriles in presence of strong base and followed by hydrogen elimination, 15 photolysis of triazole-3-thiones, 16 and oxidation of arylhydrazones. [23][24][25][26][27][28] In view of our initial successes on the utilization of hypervalent iodine reagents for the synthesis of various heterocyclic compounds under solvent-free conditions, 29,30 and because of the biological significance of 1,2,4-triazole derivatives, we decided to develop an efficient and environmentally benign synthesis of 1,2,4-triazoles that proceeds under solvent-free conditions.…”
