Pd-Catalyzed Oxidative Cross-Coupling of Perfluoroarenes with Aromatic Heterocycles
摘要:
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.

Polyfluoroaromatic compounds play crucial roles in medicinal and material science. However, the synthesis of alkylated polyfluoroarenes has been relatively underdeveloped. In this study, we devised a novel decarboxylative coupling reaction between aliphatic N-hydroxyphthalimide esters and polyfluorostyrene, leveraging the photochemical activity of electron donor–acceptor (EDA) complexes. This method
