Versuchsvorschrift

12 g of 2-fluoroacryloyl chloride and 26 g of 2,2,2-trichloroethanol were introduced into a round-bottomed flask placed in an ice bath. 17 g of triethylamine were added portionwise to the reaction mixture. After reacting for an additional 3 h, approximately 50 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 2,2,2-trichloroethanol was 52%. The yield of ester, based on the amount of 2-fluoroacrylic acid employed in the first stage, was 67%.
