The oxidative desulfurization-fluorination reaction of organosulfur compounds using an N-haloimide and a fluoride source is demonstrated to be an effective and mild fluorination method that allows us to synthesize in high yields with high chemoselectivity various types of gem-difluoro compounds, trifluoromethyl-substituted (hetero)-aromatics, trifluoromethyl ethers, and N-trifluoromethylanilines. Herein briefly summarized are the synthetic procedures as well as the scape and limitations of the. reaction. The applicability of the reaction is demonstrated by the synthesis of a difluorinated glutamic acid and novel liquid-crystalline materials having an N-trifluoromethylamino, trifluoromethoxy, or 1,2-difluoroethylene group. The fluorine-containing liquid-crystalline materials are compared with the corresponding non-fluorinated materials in respect to phase transition behaviors and electro-optical properties and shown to be suitable for not only super twisted nematic (STN) but also for thin film transistor (TFT)-addressed liquid crystals displays.
