Regiospecific monofluorinations of alpha-thio alpha-arylesters and alp
ha-thioacids were obtained by anodic and/or chemical oxidation in fluo
rinating media. This procedure provided a convenient synthesis of alph
a-fluoroesters via the CS bond cleavage induced by anodic process whil
e chemical or electrochemical oxidation of alpha-thioacids underwent a
fluoro decarboxylation, affording alpha-fluorothioethers. (C) 1998 El
