Pd-Catalyzed Olefination of Perfluoroarenes with Allyl Esters

An efficient Pd(II)-catalyzed direct olefination of perfluoroarenes with allyl esters is demonstrated. Under the typical conditions, the coupling reaction of fluorinated-arenes with allylic esters proceeded via a beta-H elimination rather than a beta-OAc elimination to give the corresponding gamma-substituted allylic esters.
