The comparative electrochemical fluorination (ECF) of selected trialkylamines and tetraalkylammonium salts was studied in order to obtain experimental data allowing a precise valuation of the ECF mechanism. The results of the investigation favour the ECF mechanism already proposed by Simons, via oxidation of F-(HF)(n) to F- and nHF, as probably the only relevant electrochemical process at the anode. For the first time some experimental proof has been obtained that a direct electrochemical oxidation of the substrate can be ruled out as a decisive step in ECF. (C) 1997 Elsevier Science S.A.
