Indirect electrochemical reduction, by means of an aromatic anion mediator, of perfluoroalkyl halides (CF3Br, n-C4F9I, n-C6F13I, I(CF2)4I) in the presence of imidazole, 4(5)-nitroimidazole, 2-methyl-5-nitroimidazole, 2-(4′-methoxyphenyl)imidazole, imidazole-2-carboxaldehyde, 4(5)-nitroimidazole-2-carboxaldehyde, 5(6)-nitrobenzimidazole, purines (adenine, hypoxanthine, xanthine, theophylline, lumazine) and pyrimidine anions (uracil, cytosine, barbituric acid) yields the corresponding C-perfluoroalkylated nitrogen bases by an SRN1 mechanism. Aromatic nucleophilic substitution of some fluorinated aryl halides 1-iodo-2-(trifluoromethyl)benzene and 1-(4′-iodo-tetrafluorophenyl)-imidazole was also investigated and it was found that 1-iodo-2-(trifluoromethyl)benzene could react successfully under redox-catalyzed conditions with imidazole, 2-(4′-methoxyphenyl)imidazole anion, and uracil anion to give the corresponding 5-(fluorinated-aryl) nitrogen bases. In the case of 1-(4′-iodo-tetrafluorophenyl)imidazole, direct electrochemical radical nucleophilic substitution with 2-methyl-5-nitroimidazole and uracil was possible in DMSO. In this way new, 4-[2′,3′,5′,6′-tetrafluoro-4′-(imidazol-1″- yl)phenyl] nitrogen bases were obtained in good yields.
Electrochemically Induced Nucleophilic Substitution of Perfluoroalkyl Halides. An Example of a Dissociative Electron-Transfer-Induced Chemical Reaction

Nucleophilic substitution of perfluoroalkyl halides can be induced electrochemically.The reaction mechanism is a slightly modified version of the classical SRN1 mechanism in which the reaction is triggered by dissociative electron transfer, not
