Palladium-catalyzed dual C-H functionalization of diaryl sulfides to form dibenzothiophenes (DBTs) by oxidative dehydrogenative cyclization is reported. This protocol afforded various DBTs in moderate to good yields with tolerance of a wide variety of substrates. Benzo[1,2-b:4,5-b']bis[b]benzothiophene was successfully synthesized by this method, which was used as an organic semiconductor for field-effect transistors.
据报道，通过氧化脱氢环化反应，钯催化二芳基硫醚的双C-H官能化反应可形成二苯并噻吩（DBT）。该方法能以中等至良好的产率得到各种二苯并噻吩，且对多种底物具有耐受性。通过该方法成功合成了苯并[1,2-b:4,5-b']双[b]苯并噻吩，其被用作场效应晶体管的有机半导体。
