“…Since then a number of radicals showing fluorine hyperfine interactions have been investigated including the anions of para and meta-fluoronitrobenzene [3,4], para-fluoroacetophenone and 2,7-difluorofluorenone [5,6]. Fluorine contact interactions have been observed in the 19F nuclear resonance spectra of substituted nickel aminotroponeimineates [7,20].…”

Electron spin resonance spectra have been observed for anion radicals derived from 2-fluoro-nitro-benzene, 3-fluoro-nitrobenzene, 2,4-difluoro-nitrobenzene, 2,5-difluoro-nitrobenzene, 4-fluoro-2-nitro-phenol, 2-fluoro-6-nitrophenol, and 3-fluoro-6-nitrophenol. All radicals were generated electrolytically in dimethoxyethane/acetonitrile solution, acetonitrile, or dimethylformamide. The radicals are generally quite stable with the exception of those from 2-fluoro-6-nitrophenol and 3-fluoro-6-nitrophenol, the latter decaying with a half-life of approximately 6 min. All spectra can be interpreted completely, and coupling constants are assigned by comparison to related compounds and consistency arguments

“…of 2.42 G is due to the ketyl liydroxyl proton, and the others to fluorine nuclei. No line width variations were observed in the ketyl spectra in contrast to those of partly fluorinated nitrobenzene anions (4,5) and the cations of perfluorinated hydrocarbons (6).…”

The ketyl radical is formed when solutions of perfluorobe~~zopheno~~e are photolyzed with 11.v. light. The radical was identified by electron spin resonance (e.s.r.) studies of the effects of solvent, tenlperati~re, chemical exchange, and deuteration on the spectra. Solvent ~n i x t~~r e s of cyclohexane and ethanol gave spectra which were very sensitive to the mole fraction of alcohol in the range 0-1%. An equilibriun~ constant for solvent nlolecule exchange has been deduced.Le radical cttyle est produit lorsqi~e des solutions de perfluorobenzophtnone sont photolystes avec de la lumiere ultraviolette.
