WebA l C l 3 + R C O O C O R → R C O + + A l C l 3 O O C R −. The positive cation electrophile reacts with benzene to produce a ketone and a hydrogen ion. Again, the hydrogen ion regenerates the catalyst. However, this time the regeneration produces a carboxylic acid (RCOOH) instead of hydrochloric acid. WebIn electrophilic aromatic substitutions, a benzene is attacked by an electrophile which results in substition of hydrogens. However, halogens are not electrophillic enough to break the aromaticity of benzenes, which require a catalyst (such as FeCl 3) to activate. See above for a detailed examination of the mechanism for bromination of benzene.
