Pd(OAc)2-Catalyzed Oxidative C-H/C-H Cross-Coupling of Electron-Deficient Polyfluoroarenes with Simple Arenes

Pd(OAc)(2)-catalyzed intermolecular C-H/C-H cross-coupling reactions between electron-deficient polyfluoroarenes and simple arenes for the synthesis of fluorinated biaryls have been developed. Deuterium-labeling experiments suggested that C-H bond cleavage of the simple arenes rather than the polyfluoroarenes is involved in the rate-limiting step.
