Regioselective Bromination of Aromatic Amines and Phenols UsingN-Benzyl-DABCO Tribromide

Abstract N-Benzyl-DABCO tribromide, a stable, solid organic ammonium tribromide, has been used as a bromine source for the regioselective and high-yielding bromination of aromatic amines and phenols. Mono-bromination proceeds well in the presence of a stoichiometric amount of bromine source at room temperature.
