A new, efficient protocol for the synthesis of di(hetero)aryl sulfides is described. Cheap and easily available arylsulfonylchlorides as a sulfur source reductively couple with electron-rich (hetero)arenes (e.g., indolizines, indoles, electron-rich benzenes, etc.) in the presence of triphenylphosphine to afford di(hetero)aryl thioethers in good yields.

3-Arylthioindoles could be synthesized in good yields via the photoirradiation of indoles and disulfides. The reaction is efficiently promoted by the catalytic amount of sodium iodide. A reactionmechanism involving the electrophilic substitution of indoles with arylsulfenyl iodine intermediates is suggested.
