Abstract : All five of the heretofore known NOF compounds (ONF, NO2F, NO3F, ONNF2, and ONF3) were synthesized and mass spectrometrically characterized. Their positive ion cracking patterns are sufficiently different to allow unambiguous assignments. Appearance potential measurements have permitted the derination of several heats of formation, and the ionization potential of nitryl fluoride was directly measured. Extensive synthesis studies with N2F2 and O2F2 as principle reagents were disappointing, but one additional NOF compound, nitrodifluoramine, O2NNF2, was produced and mass spectrometrically and energetically characterized. The compound was made from the reaction of NO2 and NF2 free radicals. O2NNF2 is a white solid at -196 C which slowly decomposes to N2F4 and NO2 even at-130C. The compounds F2NONNF2, FO2NO, FONO, ONNFNFNO, and F(3-n)N(OF)n (N=1,2,3) were shown to have marginal stabilities. (Author)
