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.

All isomers of the monomethylbenzonaphththiophenes were synthesized using photocyclization of 3-styrylbenzothiophenes.The 1-, 3-, 4-, and 5-methylbenzonaphthothiophenes were synthesized by irradiation of the corresponding methylated
