The mono- and polybromination of benzene, halogenobenzenes, toluene, p-xylene, anisole, biphenyl, benzotrifluoride, benzoic acid, p-nitro- and p-carboxytoluene, p-methoxybenzonitrile, tetralin, and naphtalene were studied in trifluoroacetic acid and its aqueous solutions in systems containing stoichiometric amounts of bromine or alkali-metal bromide and stoichiometric or catalytic (in the presence of oxygen or air) amounts of nitrogen-containing oxidizing agent (nitrogen(IV) oxide, alkali-metal nitrate or nitrite).It is suggested that the brominating agent under the investigated conditions is nitryl bromide NO2Br.Under the conditions of catalytic bromination anthracene is oxidized to anthraquinone with a preparative yield.

Reliable methods were developed for the synthesis of di-, tri-, and tetrabromoanisoles, and all the possible individual isomers were synthesized.The structures of the isomers were proved by alternative synthesis and spectral methods (PMR, IR).It was shown that the published data are incorrect in a number of cases; either the final product was assigned the incorrect structure, or the published methods led to mixture of the various isomers.
