The use of a hexafluoroisopropanol as solvent enables a mild and regioselective halogenation of a broad range of arenes and heterocycles with N-halosuccinimides in good yields. In addition, the versatility of the method is demonstrated by the development of one-pot sequential dihalogenation and halogenation-Suzuki cross-coupling reactions.
