A simple, highly efficient and economic method for the mono-bromination of number of aromatic amines and phenols using
La(NO3)3
.6H2O as a catalyst is explained. The protocol is regioselective, high-yielding and applied at room temperature to a number of
aromatic amines and phenols having electron donating or withdrawing substituents
Key words: regioselectivity, bromination, amines, phenols, catalysis
