A novel strategy for the synthesis of dibenzothiophene derivatives is established through a one-pot intramolecular cross-dehydrogenative-coupling reaction of diaryl sulfoxides followed by deoxygenation with a Rh/Ag catalytic system. The yields obtained were good to excellent (up to 96%), therefore making the described protocol an attractive option for building dibenzothiophene compounds.
