Abstract
Disclosed is a method of preparing brominated substituted anilines. A mixture in water is formed of a substituted aniline having the general formula ##STR1## where each R is independently selected from halogen, alkyl and haloalkyl from C.sub.1 to C.sub.12, aryl, alkaryl, and aralkyl from C.sub.6 to C.sub.12, R does not occupy all three 2, 4, and 6 positions, and n is 1 to 4. To the suspension is added about 1.0 to about 1.1 equivalents of bromine for each bromine atom to be substituted onto the aromatic ring of said substituted aniline. No acid is present during the reaction.
