Syntheses of heptafluoronitrosocyclobutane and nonafluoronitrosocyclopentane and their reactions with tetrafluoroethene, 1,3-hexafluorobutadiene and tetrafluorohydrazine

Abstract: Hexafluorocyclobutene and octafluorocyclopentene were reacted with nitrosyl chloride or nitrogen dioxide in the presence of KF in acetonitrile to give 80% yields of the blue heptafluoronitrosocyclobutane (I) and nonafluoronitrosocyclopentane (II), respectively. Thermal decomposition of I and II in Pyrex glass resulted in the analogous nitro compounds, CF2C-F2CF2CFN02 and CF2CF2CF2CF2CFN02. Cycloaddition reactions of I and II with tetrafluoroethene gave the oxazetidines CF2CF2CF2CFNOCF2CF2 and CF2CF2CF2CF2CFNOC… Show more

“…The peaked response at 0.5 V in Figure 2A matches that obtained at the stationary electrode in Figure 1, as expected if both responses arise from adsorbed reactant. The stable wave obtained in Figure 2B has a half-wave potential of 0.18 V, very close to the solution formal potential of the CoII1/nTMPyP couple measured by Rohrbach et al 2 This wave is therefore assignable to the reduction of ComTMPyP in solution. The steady-state limiting current measured on the plateau of the wave, 25 µ cm"2, is smaller than the value calculated from the Levich equation,8 36 µ cm"2, using the reported diffusion coefficient for ComTMPyP of 2.3 X 10~6 cm2 s"1.9 This may result from the adsorbed porphyrin's acting (8) Bard, A. J.; Faulkner, L. R. "Electrochemical Methods"; Wiley: New York, 1980; p 522.…”

“…The second term in eqn. (3) is well known from Raman spectroscopy. The effect of the relaxation on the change of bond length amounts to 0.3 pm for the C-F bond and to 2 pm for the C-CI bond, if the field strength is 0.028 a.u.…”

“…Marsden attempted to explain the "curious striking trends" [3] in (F 3) C-X bond distances, which are shorter than (H 3 ) C-X if X is highly electronegative but longer if X is of moderate or low electro negativity.…”

“…However, very few azoxy compounds with halogen or halogenated groups as substituents have been reported, such as hexafluoroazoxymethane CF 3 N(O)NCF 3 . CF 3 N(O)NF is, besides c -C 4 F 7 N(O)NF, the only azoxy compound known in which a halogen atom is bonded directly to one of the nitrogen atoms. Its first synthesis and a short characterization by vibrational and 19 F NMR spectroscopy and mass spectrometry have been reported in 1962 .…”
