Versuchsvorschrift

11 g of 2,3-dihydroxypyridine were reacted with 23.5 g of 2,3-dichloro-1,1,1,4,4,4-hexafluoro-2-butene as described in Example 2. After distillation under a high vacuum, the product was obtained in the form of colourless crystals in an amount of 15.5 g (=50% of theory). The NMR spectra showed the following characteristic absorptions: 19F-NMR: -68.5 and -81.6 ppm. 1H-NMR 4.81 ppm.
