A simple and efficient method is described for the synthesis of o-iodoaryl thioethers by the reaction of thiols and aryne. The aryne is generated from inexpensive and readily available reagents o-diiodoarene and sodium hydride. Remarkably, no disulfide substituted byproduct was observed in the reactions which is different from transition metal-catalyzed process. This method features simple operation, mild reaction conditions, broad substrate scope, and high reaction yields for many cases.

Key words: aryne, thiol, o-diiodoarene, sodium hydride, o-iodoaryl thioether
