โœฆ Synopsis

Electrophilic substitution of benzenoid compounds represents one of the most exhaustively studied aspects of organic chemistry, both mechanistically and synthetically. Within this context, there are three principal experimental procedures available for the bromination of aromatic compounds. These comprise treatment of the aromatic substrata with (a) molecular bromine (as such, or generated in situ); (b) molecular bromine in the presence of a Lewis acid catalyst; or (c) a "positive" bromine reagent (3). These three techniques,
