I n spite of the large amount of speculation in the literature concerning the mechanism for the anodic fluorination of organic compounds 1-3 and the industrial importance of both these reactions and anodic fluorine generation, there have been few electrochemical studies which attempt to investigate mechanisms in detail or to compare anode materials in liquid hydrogen fluoride. Hackerman et al. have reported the screening of a number of metals for suitability as anode materials 4 while Masson and Devynck 5 have reported the anodic limits for platinum, nickel and mercury with various electrolytes. In addition more detailed studies of certain aspects of fluorine evolution at nickel 6, platinum 7 and carbon 8 electrodes have been published. Each study has used different temperatures, reference electrodes and solution conditions, however, so that comparisons are difficult. Hence in this paper we compare the behaviour of nickel, platinum and vitreous carbon in liquid hydrogen fluoride containing sodium fluoride and report the oxidation of several organic compounds at these anodes.
