Sulfonyloxy group, displacement fluorine

Displacement of a sulfonyloxy group by fluorine can be achieved by tctra-butylpbosphonium fluoride and its mono- and dihydrofluonde under mild conditions and in good yields [I4 (equation 30)... [Pg.212]

With certain exceptions, primary fluorination of carbohydrate derivatives is very facile. Fluoride displacement of sulfonyloxy groups by potassium, or cesium, fluoride in 1,2-ethanediol and a variety of other solvents has frequently been used. Tetrabutylammonium (sometimes tetraethylammonium) fluoride in dipolar, aprotic solvents (mainly ace-... [Pg.204]
