ResumoThe mechanism of electrochemical bromination of aromatic compounds in anhydrous acetic acid has been investigated. Bromine ion gives two waves in anhydrous acetic acid, by addition of p-xylene or toluene. At the first wave Br2 is formed which gives rise to an oxidizable complex with the aromatic substrate. At the potential of the first wave this oxidizable complex always yields the aromatic ring substituted bromo derivative and monobromoacetic acid. At the second wave the aromatic substrate oxidation occurs depolarized by Br−, and probably via the same oxidizable complex that is formed at the first wave. The formation of aromatic ring-substituted bromo derivative and monobromoacetic acid takes place.
