Bromination and iodination of the aromatic compounds have efficiently been carried out at room temperature and $70^{\circ}C$, respectively, in short reaction times using orthoperiodic acid/sodium bromide (1:2) and orthoperiodic acid/sodium iodide (1:2) in water to prepare the corresponding halo compounds with excellent yields.
