Versuchsvorschrift

A solution of 9.2 g (0.09 mol) of triethylamine in 25 ml of ether was added dropwise to a stirred solution of 17.6 g (0.10 mol) of trifluoromethylmalonyl fluoride in 50 ml of ether at -80°C. To the resulting suspension of solid was added 14.1 g (0.11 mol) of ethyl fluorosulfate and the mixture was then allowed to warm to 25°C with stirring. The homogeneous reaction mixture developed two layers after standing overnight. Distillation gave 15 g (74%) of ethyltrifluoromethylmalonyl fluoride, bp 54°-56°C (260 mm), identified by ir.
