A highly efficient and environmentally friendly method for catalytic chalcogenylation of imidazopyridines, imidazopyrimidines, indoles, and pyrrolo[2,3-b]pyridines with dichalcogenides has been developed by using CuI as catalyst under air. The reactions proceed smoothly to give the desired products in moderate to excellent yields, without the presence of other additive.
