  Dinitroamide ion was oxidized at a potential of 2.3-2.4 V and reduced at -0.4 V (Ag/AgCl reference electrode). The photochemical oxidation of a solution of a dinitroamide salt and the spin trap, N-tert-butyl-alpha-phenylnitrone (PBN), in acetonitrile or dichloromethane gave rise to a weak 3 x 5 lines EPR spectrum, assigned to the formal spin adduct of dinitroamino radical and PEN, (NO2)(2)N-PBN'. The reaction is suggested to involve oxidation of PEN to its radical cation, followed by capture of dinitroamide ion by the latter. The thermal oxidation of similar solutions gave rise to a different, much more intense EPR spectrum, the hyperfine splitting constants of which showed the presence of three different nitrogens and the absence of the v.-hydrogen of PEN. The spectrum was assigned to O2N-N=C(Ph)-N(O')(Bu-t), formally derived from the dinitroamino spin adduct by elimination of nitrous acid. Mechanistically, this transformation presumably occurs by one-electron oxidation of (NO2)(2)N-PBN', followed by loss of a proton and NO2, from the nitrosonium ion intermediate formed.

  Advanced bipropellant fuels with fast ignition upon mixing with storable oxidizer (N2O4, nitric acid) have been synthesized and demonstrated. The bipropellant fuels are based upon salts containing dicyanamide or tricyanomethanide anions and employ at least two hydrazine functionalities in the cations.
