Dioxygen difluoridei (or r;he 02F radical) undergoes the fluoride abstraction reaction with strong Lewis acids at low temperatures to give ?table dioxygenyl salts. Oxygen difluoride under- goes a similar reaction at elevated temperatures. 20F2 + SbF5 200° , 02SbF6 + F2 Although considerable doubt now exists about the existence of trioxygen trifluoride, the trifluoromethyl derivative CF3OOOCF3 is known as well as the peroxide m300CF3. %e iuthors 3re pot aware of reports of the simple ether (CF3)2O, although the sul- ,fide (CF3)pS is stable at 40OoC. 111, Nitrogen Fluorides and Derivatives The reported nitrogen fluorides, their derivatives and some of their y-ogertics ire summarized in Table 11. The NF molecule is known only as a reactive intermediate which dimerizes readily to N2F2. It has been observed by flash photolysis of the NF2 radical in an wgon matrix at 4OK and bj pyrolysis of N2F4 at high dilution in argon at 2550'K. The NF2 radical is well established to exist in equilibrium with N2F4 in -:.:logy to the Pj204-T;02 equilibrium N2F4 2*2 The structure of LTF2 (N-F = 1.36 i; LFNF = 103') is closely related to that of NF3. The iF2 radical has fundamental stretching frequencies at 1074 and 935 cm-l in the i:frxed. In the ultraviolet, IF2 absorbs at 260 mp to give an excited radical, :92*, which decomFoses to NT and F., but may undergo unique reactions. The reac- L. ~~01.s of I92 are discussed in the section on N2F4. , Nitrogen trifluoride is commercially available and its properties are -;,x~'lL k.r.owr.. It has an amonia-like structure with N-F = 1.37 1 and LFNF = 103'. Only 57 )..cal/mol are requiredto dissociate a F- atom from NF3, but an average of 71 kcal/mol are required for. each of the remaining two N-F bonds of the stable NF2 rodic-:l. i93 is relatively-unreactive at mild temperatures, but functions as a fluorir.aticg ngent at elevated temperature. The most interesting reaction of NF3 to be reported recently is that with fluorine and Lewis acids to give stable salts of the I.5'4' ion.
