Microwave-assisted iridium-catalyzed meta C-H borylation followed by copper-promoted C-S bond coupling reactions in one pot is reported. This approach enables the syntheses of aryl thioethers in short reaction times (within 2.5 hours). The system shows good functional-group compatibility, as chloro, trifluoromethyl, fluoro, and pyridine groups are tolerated by the reaction conditions. Both aryl and alkyl thiols are coupled smoothly. The products were formed with excellent regioselectivity in meta position.

A generalprocedure for the synthesis of aryl thioethers and aryl selenides in one-pot through sequential iridium-catalyzed C–H borylation and copper-promoted C–S and C–Se bond formation is described. Functional groups including chloro, nitro, fluoro, trifluoromethyl, and nitrogen-containing heterocycles were all tolerated under the reaction conditions. Importantly, not only aryl thiols and selenides
