SYNTHESIS OF AROMATIC POLYHALOGENATED HALOMETHYL COMPOUNDS

The present invention discloses a process for the preparation of highly pure Pentabromobenzyl bromide, PBB-Br, wherein the benzylic bromination reaction is carried out in a suitable organic solvent in the presence of water and wherein the reaction temperature is such that it is sufficient to activate the initiator but not high enough to consume a substantial amount thereof.

Polybromoaromatic compounds: VIII. Specific features of pentabromobenzyl bromide hydrolysis in some solvents

Hydrolysis of pentabromobenzyl bromide in aqueous solvents dioxane, dimethyl sulfoxide, and dimethylformamide results in 2,3,4,5,6-pentabromobenzyl alcohol, and in two latter solvents as side products arise respectively pentabromobenzaldehyde and 2,3,4,5,6-pentabromobenzyl formate.

CATALYTIC AND STOICHIOMETRIC BROMINATION OF AROMATIC COMPOUNDS IN AQUEOUS TRIFLUOROACETIC ACID IN THE PRESENCE OF NITROGEN-CONTAINING OXIDIZING AGENTS

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.
