A general palladium-catalyzed aryl(alkyl)thiolation of various substituted unactivated arenes is accomplished for the synthesis of diverse unsymmetrical diaryl(alkyl) sulfides in good yield employing electrophilic sulfur reagent 6 derived from succinimide. The developed strategy was coupled with intramolecular arylation of a C-H bond to afford dibenzothiphene derivatives, an important moiety in material science as organic semiconductors.
