A number of new [1,2,4]triazolo[4,3‐b]pyridazines were prepared by either cyclocondesation of substituted hydrazinopyridazines with orthoesters or oxidative cyclization of their hydrazone analogs in nitrobenzene as an oxidizing agent. A host of other new [1,2,4]triazolo[4,3‐b]pyridazine derivatives were synthesized by sequential treatment of the latter compounds with carbon disulfide and alkyl halides
许多新的[1,2,4]三唑并[4,3- b ]哒嗪是通过用原酸酯环化取代的肼并哒嗪或将其类似物在氧化剂硝基苯中氧化环化制得的。通过依次用二硫化碳和烷基卤化物处理后一种化合物,可以合成许多其他的[1,2,4] triazolo [4,3- b ]哒嗪衍生物。
