Abstract

Electrochemical regioselective bromination of electron-rich aromatic rings using stoichiometric tetrabutylammonium bromide ( n Bu4NBr) has been accomplished under mild conditions. This protocol provides an environmentally friendly and simple way for the construction of C–Br bond in moderate to high yields with wide functional group tolerance.
