Sodium Fluoride → HCID 14897839, compound

Participants

Reaction Steps

In 20 ml of anhydrous acetonitrile 0.50 g (4.67 mmoles) of 2.6- dimethylpyridine and 0.803 g (4.67 mmoles) of sodium trifluoromethanesulfonate as the XM reactant were dissolved, and to the resultant solution a mixed gas of fluorine and nitrogen (1:9) was added at a rate of 30 ml/min. at -40° C. under vigorous stirring. The amount of the fluorine gas introduced amounted to 8.93 mmoles. After the completion of the reaction, sodium fluoride was filtered and the solvent was distilled off. The resultant residue was recrystallized from THF to give 0.88 g (yield: 73%) of N-fluoro-2,6-dimethyl-pyridinium trifluoromethanesulfonate. The resultant product was further recrystallized with THF/acetonitrile to obtain 0.82 g (yield: 69%), the physical properties of which are shown in Table 6.
