Coplanar benzo[1,2-b:4,5-b′]bis[b]benzothiophenes (1a, 1b) for the application in organic field-effect transistors were synthesized by a simple two-step procedure involving triflic acid induced ring-closure reaction; such solution processed devices show a hole mobility of up to 0.01 cm2 V-1 s-1.

Much interest has been paid to cyclic diaryliodonium salts as bis(electrophile)s in transition-metal-catalyzed annulation reactions to produce polycyclic (hetero)aromatic hydrocarbons. Herein, we report that dibenziodolium triflates smoothly react with potassium thioacetate in the presence of CuCl2in THF or DMSO at 100–110 °C to afford the corresponding dibenzothiophenes in good-to-high yields. The coupling reaction tolerates reactive functional groups such as chloro and cyano and serves as a facile and reliable method for the synthesis of unsymmetrical dibenzothiophenes.

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.
