A new method was demonstrated to overcome the selectivity issue of radical–radical cross-coupling toward the synthesis of asymmetric diaryl thioethers. The preliminary mechanism was revealed by radical-trapping experiments, DFT calculations, and kinetics, etc., indicating that the C–S bond formed through cross-coupling of a thiyl radical and an aryl radical cation. Moreover, the formation of an aryl
