Abstract

During uv irradiation of benzophenone in solutions containing fluorine-substituted phenols and anilines the 19 F magnetic resonance spectra of the phenols or anilines showed strong CIDNP signals. These phenomena are explained by a mechanism involving diphenylhydroxymethyl and phenoxyl (anilinyl) radicals. The enhancement patterns indicate that the hyperfine coupling constants of ortho and para (meta) fluorine nuclei in phenoxyl and anilinyl radicals are positive (negative).
