A copper-catalyzeddirectpropargylation of polyfluoroarenes with secondarypropargylphosphates has been developed. The reaction proceeds under mild reaction conditions with high efficiency and regioselectivity and provides a concise and straightforward method for the synthesis of polyfluoroarylated derivatives of interest in both life and materials science.

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
