4-Cyano-3,5-difluorophenol, useful as intermediate in the manufacturing of liquid crystals, was prepared by the regioselective iodination of 3,5-difluorophenol to give 4-iodo-3,5-difluorophenol, which was then converted to 4-cyano-3,5-difluorophenol under a mild reaction condition. The reaction products were characterized by spectroscopic methods and confirmed by comparison of these analytical data with reported values in the literatures.
