Iodobenzene can be used as a recyclable catalyst in combination with m-chloroperbenzoic acid as the terminal oxidant for an efficient and regioselective monobromination of electron-rich aromatic compounds. The bromination of electron-rich aromatic compounds with lithium bromide was fast in tetrahydrofuran at room temperature, providing regioselective monobrominated products in good yields.
