摘　　要：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.The treatment of 5 amino 1 (4 chlorophenyl) 1,2,3 triazol 4 carbohydrazide with equimolecular aryl isothiocyanate gave new derivatives 1 a—l .
