A palladium-catalyzed remote δ-C−H selenylation of arylethylamidederivatives with readily available diselenides has been reported. This protocol relies on the use of a removable picolinamide directing group to access unsymmetrical diaryl selenides in 45–98% yields. Furthermore, the inactivated δ-C(alkenyl)−H bond was also compatible in this reaction and afforded the thermo-dynamically unfavorable
