Catalysed bromination of aromatic substrates

The kinetics of bromination of a reactive substrate like anisole and a less reactive substrate like p-nitrophenol has been investigated in acetic acid medium with iodine added to accelerate the reaction. The effective catalyst has been shown to be iodine bromide. The experimental results obtained from a study of the phenomenon of catalytic maximum in these reactions are in good agreement with the theoretical expectations. © 1970 Indian Academy of Sciences.
