The bromination of 2-benzoylpyrrole with copper (II) bromide in the homogenous and heterogenous phase is described, giving 4- and 5-monobromo derivatives whose ratio decreases as the temperature is increased.The same reaction with copper(II) chloride in acetonitrile at 60 deg C produces 5-chloro-2-benzoylpyrrole as the major product. 4,5-Dihalopyrroles in good yields are obtained with an excess of halogenating agent.
