Abstract：

A　potassium　hydroxide/dimethyl　sulfoxide　(KOH/DMSO)　superbase-promoted　method　for　the　synthesis　of　2-substituted　benzothiophenes　has　been　developed　via　photoinduced　intermolecular　annulation　of　2-halothioanisoles　with　terminal　alkynes　at　ambient　temperature.　The　present　protocol　uses　commercially　available　2-halothioanisoles　as　substrates　and　visible　light　as　energy　force,　which　offers　a　wide　range　of　benzothiophenes　regioselectively　in　moderate　to　good　yields.　Such　a　facile　and　effective　transformation　will　provide　an　environment-friendly　approach　to　the　synthesis　of　benzothiophene　derivatives.　©　2016　WILEY-VCH　Verlag　GmbH　&　Co.　KGaA,　Weinheim.
