Practical and straightforward method for regioselective C-S bond formation accomplished by copper-catalyzed regioselective C-F substitution of electron-deficient perfluoroarenes with aryl thioacetates or benzyl thioacetate has been developed. Because of its high reaction efficiency, good chemoselectivity and regioselectivity, and excellent functional-group compatibility, this protocol provides a useful and operationally simple access to polyfluoroaryl thioethers used for drugs and material chemistry.
