Palladium Catalyzed Aryl(alkyl)thiolation of Unactivated Arenes

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 <b>6</b> 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
