properties | 2-fluoro-6-trifluoromethyl pyridine is a colorless to light yellow liquid at normal temperature and pressure. |
uses | 2-fluoro-6-trifluoromethyl pyridine can be used as pharmaceutical and organic synthesis intermediates for the preparation of pesticides, bactericide, etc., in the organic synthesis conversion, the fluorine atom in the structure is easily attacked by the nucleophilic reagent by the influence of the electron deficiency of the pyridine ring to obtain the corresponding defluorinated functional group. |
preparation method | at 0°C, to the vacuum-dried pressure-resistant tube, 2-chloro-6-trichloromethylpyridine, hydrofluoric acid, ferric chloride and solvent were slowly added, and the resulting mixture was stirred at 170 ° C. For 4 hours, the progress of the reaction can be monitored by gas chromatography, the reaction is cooled to room temperature, and the saturated sodium carbonate aqueous solution is slowly added to the reaction system after the reaction is completed to neutralize the acid generated in the reaction process, the pH of the reaction system was adjusted to be alkaline. After extraction with ethyl acetate, the organic layer was dried and spin-dried to obtain the desired product. Fig.2-synthesis of fluoro-6-trifluoromethyl pyridine |
