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.
活化的2-(烷基亚磺酰基)噻吩被烷基或芳基硫醇的亲核取代得到相应的2-(烷硫基)-或2-(芳硫基)-取代的噻吩。当使用硫醇根阴离子代替硫醇根时,亚砜还原是主要反应。
