Abstract : It was postulated that changing the chemical environment of unstable NF moieties might yield new energetic materials having desirable properties. Known high-energy species were used for the synthesis of NF compounds. The reaction of NFCl2 with BF3 yielded a 1:1 adduct which is best formulated as NCl2 + BF4 -. The NCl2 + cation behaved as a chlorinating agent, inasmuch as reaction with HNF2 yielded primarily NF2Cl. The compound NFCl2 behaved as a source of NF, rather than of the NFCl radical, since (1) N2F2 was a frequent reaction product, and (2) no evidence was obtained for the formation of N2F3Cl or N2F2Cl2 from a variety of reactions involving NFCl2, and under a variety of experimental conditions. Reactions involving FN(Cl)CO2Et and FN(Cl)CO2i-Pr with Hg led to complex mixtures of mercurials which contained Hg(NFCO2Et)2 and Hg(NFCO2i-Pr)2, respectively. Reactions involving the mixture of mercurials obtained from FN(Cl)CO2i-Pr and Hg with CH3COCl and with Br, yielded CH3CONFCO2i-Pr and FN(Br)CO2i-Pr, respectively. All attempts to prepare i-Pr-O2 CNFNFCO2i-Pr - a possible precursor to N3F5 and N4F6 - were unsuccessful. Other synthetic routes leading to N sub (x) F sub (x+2) were also unsuccessful. Attempts to prepare the cations N2F5 + and (C(NF2)3)+, in the form of their SbF6 - salts led to known products, including N2, NF3, and CF4.
