Reaction of 5-aryl-3-chloro-4-phenyl-1,2,4-triazoles (1 & 2) with hydrazine hydrate afforded the hydrazino derivatives 3 and 4. Reaction of 3 and 4 with carboxylic acids, CS2 and phenylisothiocyanate gave the s-triazole-fused ring systems 5–12. On the other hand, reaction of 3 and 4 with nitrous acid gave tetrazole-fused ring systems 13 and 14, respectively. Mannich reaction on compounds 9 and 10 afforded
5-芳基-3-氯-4-苯基-1,2,4-三唑(1和2)与水合肼反应得到肼衍生物3和4。3和4与羧酸、CS2和异硫氰酸苯酯反应得到s-三唑稠环系统 5-12。另一方面,3和4与亚硝酸反应分别得到四唑稠环系统13和14。化合物 9 和 10 的曼尼希反应得到曼尼希碱 15 和 16。
