Аннотация: Nitration of 6-R-4-phenylpyrazolo[3,4-d][1,2,3]triazoles at the phenyl substituent is accompanied by the triazole ring opening to give new 3-R-4-diazo-1-(di)nitrophenylpyrazole- 5-nitrimines. Chemical and physicochemical properties of the prepared compounds are reported.

Ключевые слова: nitration, pyrazoles, 1,2,3-triazoles, ring opening, pyrazolo[3,4-d][1,2,3]triazoles, energetic properties, X-ray diffraction analysis, differential scanning calorimetry.
