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.

An efficient procedure for the formation of C–S bonds via C–H functionalization was developed for the synthesis of aryl sulfides in good to excellent yields using TBAI–HBr system promoted direct sulfenylation of various compounds, such as phenols, pyrazolones, indoles and related heteroarenes. Low cost and widely available arylsulfonyl chlorides were used as the sulfur source to provide various sulfur-containing
