Versuchsvorschrift

12 g of 2-fluoroacryloyl chloride and 27 g of 1,1,1,3,3,3-hexafluoro-2-propanol were introduced into a round-bottomed flask placed in an ice bath. 16 g of triethylamine were added portionwise to the reaction mixture. After reacting for an additional 3 h, approximately 70 ml of water were added. The aqueous and organic phases were subsequently separated and the organic phase was analysed by GC. The conversion of the 1,1,1,3,3,3-hexafluoroisopropanol was 68%. The yield of ester, based on the amount of 2-fluoroacrylic acid employed in the first stage, was 66%.
