Some new 1,2,3-triazolo[4,5-d]-1,2,4-triazolo[4,3-b]pyridazines were prepared starting from the corresponding 1,2,3-triazolo[4,5-d]pyridazines via the formation of the 1,2,4-triazole ring, by condensation of an appropriate monocarbon fragment with the 4-hydrazino substituent and the nitrogen atom in the 5 position of the heterocycle. Condensation of 4-phenylhydrazino substituted derivatives with formic
从相应的1,2,3-三唑并[4,5-]开始,制备了一些新的1,2,3-三唑并[4,5- d ] -1,2,4-三唑并[4,3-b]哒嗪。d ]哒嗪通过形成适当的单碳片段与4-肼基取代基和杂环5位上的氮原子缩合而形成1,2,4-三唑环。4-苯基肼基取代的衍生物与甲酸的缩合得到两性离子化合物。
