Abstract
Anodic fluorination of benzo[ B]thiophenederivatives provided a complex mixture of di- and trifluorinatedproducts. On the other hand, anodic fluorination of 3-oxo-2,3-dihydrobenzo[ B]thiophene and methyl 3-oxo-2,3-dihydrobenzo[ B]thiophene-2-carboxylate gavethe corresponding monofluorinated products -selectivelyin moderate yields. Anodic fluorination of methyl α-(2-cyanophenylthio)acetatefollowed by intramolecular cyclization provided 3-amino-2-fluorobenzo[ B]thiophene in excellent yield.
