Alkylation of 4,5-disubstituted 4H-1,2,4-triazole-3-thiols with methyl chloroformate and ethyl chloroacetate chemoselectively afforded the corresponding S-alkyl derivatives, whereas the alkylation of 5-benzyl-4-phenyl-4H-1,2,4-triazole-3-thiol with methyl 3-bromopropanoate gave an inseparable mixture of S- and N-alkylation products. Hydrazinolysis of S-(5-benzyl-4-phenyl-4H-1,2,4-triazol-3-yl) methyl
4,5-二取代的4 H -1,2,4-三唑-3-硫醇与氯甲酸甲酯和氯乙酸乙酯的烷基化反应产生相应的S-烷基衍生物,而5-苄基-4-苯基-4 H的烷基化-1,2,4-三唑-3-硫醇与3-溴丙酸甲酯形成不可分离的S-和N-烷基化产物混合物。的肼解小号- (5-苄基-4-苯基-4- ħ -1,2,4-三唑-3-基)甲基碳酸酯所涉及的异常裂解与形成的初始4,5-二取代的1,2,4-三唑的和肼甲酸甲酯。
