Versuchsvorschrift

To 17.6 g (0.10 mol) of trifluoromethylmalonyl fluoride and 50 ml of ether stirred at -80°C was added dropwise a solution of 9.2 g (0.09 mol) of triethylamine in 25 ml of ether. Then 12.5 g (0.12 mol) of 1-chloro-3-methyl-2-butene was added, and the mixture was stirred at 25°C until homogeneous. After standing at 25°C for 3 days, the mixture was distilled to give 3.9 g (16%) of (3-methyl-2-butenyl)-trifluoromethylmalonyl fluoride, bp 43°-45°C (20 mm); ir (CCl4): 3.31, 3.37 and 3.42 (CH), 5.36 (C=O) and 7.5-8.5 μ (CF).
