Abstract

Abstract: The treatment of 5-amino-1-(4'-chlorophenyl)-1, 2, 3-triazol-4-carbohydrazide with equimolecular aryl isothiocyanate gave new derivatives 1 _a—l . Twelve title compounds were obtained in 42% to 87% yields when compounds 1_a—l were respectively treated with sodium hydroxide aqueous solution(2 mol/L). The products of Dimroth rearrangement were not observed in the experiment. The structures of all the compounds were confirmed by means of IR, ¹H NMR, MS and elementary analysis.

Key words: 1,2,3-Triazole, 1,2,4-Triazoline-5-thione, Heterocycle, Synthesis
