Electrochemical Regioselective Bromination of Electron-Rich Aromatic Rings Using
n
Bu4NBr
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.
diacetate mediated method for selective chlorination, bromination, and iodination of indole C–H bonds using sodium halide as a source for analogous halogenations. The combination of NaX and phenyliodine diacetate provides an invincible system for halogenation of indoles. This protocol was compatible with a wide array of indole substrates and provides straight forward access to potential halogenated arenes
