Palladium‐catalyzed dual CH 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.
