Pd-Catalyzed Oxidative Cross-Coupling of Perfluoroarenes with Aromatic Heterocycles

A straightforward and practical method for direct Pd(OAc)(2)-catalyzed oxidative cross-coupling of electron-deficient perfluoroarenes with aromatic heterocycles has been developed. Because of its low catalyst loading (2.5 mol %), high reaction efficiency, good chemo- and regioselectivity, and excellent functional-group compatibility, this protocol provides a useful and operationally simple access to perfluoroarene thiophene structures of interest in functional materials for electronic devices.
