摘要: A convenient metal-free and solvent-free iodine-catalyzed regioselective greener protocol to access different types of unsymmetrical chalcogenides with nitrogen- or oxygen-containing arenes through oxidative C–Se/C–S formation via direct C(sp2)–H bond activation was developed. The products were obtained in good excellent yields using [O N]-containing arenes, half equiv. various odorless diorganyl dichalcogenides (S/Se), iodine (20 mol%) as the catalyst 3 DMSO oxidant, applying MW irradiation for 10 min.
