An efficient, Pd(OAc)(2) catalyzed method for direct olefination of highly electron-deficient perfluoroarenes was developed. The reaction scope includes a series of activated and nonactivated alkenes in moderate to high yields with moderate to high regio- and stereoselectivities.

sole oxidant and no redox mediator. Arenes with either electron-donating or electron-withdrawing groups can be functionalized in this way. Experimental data on the reaction with toluene as the model arene shows that the C−Hactivation step is turnover limiting and that the ligand structure is crucial to facilitate the reaction, which supports the involvement of the pyridone fragment in the C−H activation
