The Electrochemical Fluorination of Trifluoromethyl-substituted Benzenes

Abstract
The electrochemical fluorination of benzenes containing one or two trifluoromethyl groups has been carried out. They afforded perfluorocyclohexane derivatives with the trifluoromethyl group in good yields. Chlorobenzenes containing a trifluoromethyl group yielded chlorinecontaining perfluorocyclohexane derivatives carrying the trifluoromethyl group. Trifluoromethylbenzonitriles gave perfluoro(dimethylcyclohexane)s, whereupon the nitrile group was converted into a trifluoromethyl group, thus releasing nitrogen trifluoride. The electrochemical fluorination of a trifluoromethylnaphthalene gave perfluoro(methyldecahydronaphthalene) only in a small yield.
