allows the selective synthesis of the polyfluoroaryl-heteroarenes in moderate to high yields, without C–H bond functionalization of the polyfluorobenzene ring. In most cases, low loading of Pd(OAc)2 catalyst (0.5–1 mol %) was employed. Then, from these heteroarylated polyfluorobenzenes, the palladium-catalyzed C–H bond functionalization of the polyfluorobenzene ring allows the synthesis of heteroarylated
