3,3′-(Diazene-1,2-diyl)bis[4-(nitroamino)-1,2,5-oxadiazole 2-oxide]

Abstract 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 HNO 3/(CF 3CO) 2O in molar ratio 15:3 in CCl 4 at ？5 °C. The structure of 3,3′-(diazene-1,2-diyl)bis[4-(nitroamino)-1,2,5-oxadiazole 2-oxide] was confirmed by means of 1H, 13C, 14N-NMR, IR spectroscopy and high resolution mass spectra (HRMS). View Full-Tex
