Silver-catalyzed Meerwein arylation: intermolecular and intramolecular fluoroarylation of styrenes.

The first example of silver-catalyzed intermolecular and intramolecular Meerwein fluoroarylation of styrenes with aryl diazonium salts has been developed. This reaction is operationally simple, scalable and proceeds under mild conditions. Furthermore, fluorinated dihydrobenzofurans and indolines were easily accessed using this method.
