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.

A direct thiolation of methoxybenzenes with various thiols has been developed. The protocol uses inexpensive reagents: catalytic iodine in the presence of DTBP. Importantly, no base or ligand was necessary. This method opens a new avenue to a variety of valuable thioethers that would be more difficult to access with traditional methods.
