Ring bromination of aromatic compounds using 1,3-dibromo-5,5-dimethylhydantoin in dichloromethane is promoted by the addition of strong acids.Both organic and inorganic acids whose pKa values are lower than -2 showed the promoting effect.This acid-catalyzed bromination is both practical and effective, even for aromatics having electron-withdrawing substituents.
