Ambrose, James F. published the artcileElectrochemical and spectroscopic properties of cation radicals. III. Reaction pathways of carbazolium radical ions, COA of Formula: C18H12FN, the publication is Journal of the Electrochemical Society (1975), 122(7), 876-94, database is CAplus.
The anodic oxidation pathways of seventy-six ring-substituted carbazoles are examined using electrochem. and spectral techniques. The reactivity of the substituted carbazole cation radicals is also determined The C-3, C-6, and N-9 positions are extremely reactive; if these sites are not blocked by inert substituents the cation radicals generated by electrolytic oxidation react rapidly via coupling-deprotonation. In some cases, substituents are eliminated from the C-3 and C-6 positions in the cation radicals followed by coupling to form substituted bicarbazyls. In other cases, relatively stable cation radicals are obtained and their EPR and visible absorption spectra are observed The reactivities of substituted carbazole cation radicals are greater than those of analogous di- and triphenylaminium ions due to the planarity of the carbazole aromatic rings.
