The nitramino derivatives of furoxans are of specific interest as precursors for the preparation of high energy salts with nitrogen-rich cations. In this communication, the 3,3'-(diazene-1,2-diyl)bis[4-(nitroamino)-1,2,5-oxadiazole 2-oxide] was prepared via nitration of available 4,4'-diamino-3,3'-diazenofuroxan; the best yield of the target compound was achieved under the action of nitrating system HNO3/(CF3CO)(2)O in molar ratio 15:3 in CCl4 at -5 degrees C. The structure of 3,3'-(diazene-1,2-diyl)bis[4-(nitroamino)-1,2,5-oxadiazole 2-oxide] was confirmed by means of H-1, C-13, (NMR)-N-14 spectroscopy and high resolution mass spectra (HRMS).
