was developed for the regioselective formation of 2-aryl- or 2,5-diarylselenophenes via a palladium-catalyzeddirectarylation. This protocol is suitable for a wide range of aryl halides containing different functional groups. The 2-arylated substrates can undergo an additional regioselective directarylation event furnishing symmetrical or unsymmetrical 2,5-diaryl selenophenes in good yield. Competition
