Hermann, Tobias S.; Klapötke, Thomas M.; Krumm, Burkhard (2018): Formation and Characterization of Heavy Alkali and Silver Salts of the 4-Nitro-pyrazolo-(3,4-c)-furazan-5-N-oxide Anion. In: Propellants Explosives Pyrotechnics, Vol. 43, No. 1: pp. 54-61

The nitration of 3-amino-4-chloro-oximidofurazan resulted in the formation of the unexpected anionic heterocycle 4-nitro-pyrazolo-(3,4,c)-furazan-5-N-oxide. Various experiments such as changing the reactants, oxidation or methylation were attempted to elucidate the reaction conditions and mechanism. The heavier alkali and silver salts of the above-mentioned heterocycle were isolated. The salts were characterized and investigated by means of NMR, vibrational spectroscopy, X-ray diffraction and energetic properties.
