Electrochemical fluorination of anisole furnished 2- and 4-fluoroanisoles in a 3:1 ratio, guaiacol, and 4,4'-dimethoxydiphenyl ether. Phenylacetonitrile alongside the fluorination in the ring suffered the transformation of the cyano group into a trifluoromethyl. 4-Bromobenzamide was fluorinated to a high conversion mostly in the ring to afford predominantly 4-bromo-3,3,6,6-tetrafluoro-1,4-cyclohexadienecarboxamide. 4-Bromonitrobenzene in a low yield gave 4-bromofluoronitrobenzene and 3,4-dibromofluoronitrobenzene. 3-Bromo-nitrobenzene and 1,4-dichlorobenzene did not undergo fluorination. In the course of the electrolysis of the 4-bromobenzamide and 4-bromonitrobenzene in anhydrous HF apart the fluorination occurred also the bromination of the substrates.
