Abstract
Ring bromination of alkylbenzenes at room temperature was effectively performed on aromatic substrates catalyzed by zeolite 13X or mordenite after introduction of iron(III) ions. Other zeolites and ions were also studied. Almost quantitative yields of p- and o-bromo derivatives without dibromo or side-chain derivatives were obtained after 3-4 h when the reaction was performed in the dark. Bromination of benzene was not complete even at reflux temperature. The catalyst may be recycled many times for practical applications.
