Regioselective Bromination of Anilines in the Presence of Nitrosonium Hydrogensulfate in Concentrated Sulfuric Acid

Regioselective Bromination of Anilines in the Presence of Nitrosonium Hydrogensulfate in Concentrated Sulfuric Acid

Reaction of aniline, o- and m-substituted anilines or N,N-dialkylanilines with bromine and nitrosonium hydrogensulfate in concentrated sulfuric acid leads to the corresponding 4-bromoanilines but no bromination takes place in the absence of nitrosonium salt.
