Abstract
A mild and efficient synthesis of various 3-brominated azaindoles and diazaindoles
was developed by regioselective halogenation of the parent systems. This practical
and high-yielding transformation was achieved with copper(II) bromide in acetonitrile
at room temperature.
Key words
3-brominated azaindoles - regioselective halogenation - copper(II) bromide
