The palladium-catalyzed direct arylation of 1,2,4-oxadiazoles proceeds efficiently at low catalyst loading (0.5 to 1 mol %) with the decisive assistance of sterically constrained ferrocenyldiphosphane ligands. This protocol tolerates electron-donating and electron-withdrawing substituents on the (heteroaryl)arylhalide.
