Comparative electrochemical fluorination (ECF) of ethanesulfonyl chloride and fluoride via the Simons process has been investigated. In contrast to previously reported data, the electrochemical fluorination of C2H5SO2Cl only results in low yield of C2F5SO2F and the observed product distribution pattern indicates the strong influence of the chlorination process on the decomposition of the starting material. Ethanesulfonyl fluoride serves as a suitable starting material for the high-yield syntheses of pentafluoroethanesulfonyl fluoride and pentafluoroethanesulfonic acid. The electrochemical reduction of alkane- and chloroalkane-sulfonyl chlorides was investigated by cyclic voltammetry in order to explain the behaviour of these compounds during the Simons process.
