Direct C-arylation of polyfluoroarenes with diaryliodonium salts via Pd(OAc)(2)-catalysis

A novel approach towards the Pd-catalyzed arylation of electron-deficient polyfluoroarenes with diaryliodonium salts was developed. The desired fluorinated biaryls were synthesized in good yields. The mechanistic insights involving the Pd-II/IV catalytic
