Abstract
A process for preparing a fluorinating reagent from a calcium-containing compound is disclosed. The process bypasses the requirement to form hydrofluoric acid. The fluorinating reagent can be used to prepare high-value fluorochemicals.
Claims20
A method of fluorinating an organic compound, the method comprising:
- combining an activated fluorination reagent, a powder x-ray diffraction spectrum of the activated fluorination reagent comprising characteristic 20 reflections at about 21.9°, 30.3°, or 43.4°, with the organic compound;
- and
- fluorinating the organic compound to produce an organo-fluorine compound.
A fluorination reagent comprising:
- calcium and fluorine, the fluorination reagent having a powder x-ray diffraction spectrum which comprises characteristic 20 reflections at about 18.0°, 18.7°, 21.9°, 22.6°, 24.5°, 25.4°, 26.5°, 27.0°, 28.0°, 29.2°, 30.3°, 31.6°, 33.0°, 34.8°, 36.4°, 37.7°, 39.5°, 40.4°, 41.7°, 42.4°, 43.4°, 46.1°, 48.4°, 49.4°, 52.8°, or 53.9°.
