                                    The nucleophilic substitution of activated 2-(alkylsulfinyl)thiophenes with alkyl- or arylmercaptans gives the corresponding 2-(alkylthio)- or 2-(arylthio)- substituted thiophenes. When thiolate anion is used instead of thiol, sulfoxide reduction is the main reaction.
