실험 절차
A 100-g sample (0.5 mole) of 2,3-dichloro-2,3,3-trifluoropropionyl fluoride, prepared as shown in Example 11, was added dropwise to a stirred suspension of 34 g (0.25 mole) of aluminum chloride in 200 ml of methylene chloride. The reaction mixture was stirred for two hrs, and the volatile portion was distilled under reduced pressure into a Dry-ice cooled trap. Redistillation gave 70.6 g (66%) of 2,3-dichloro-2,3,3-trifluoropropionyl chloride as a colorless liquid: bp 87.5°-88°; nd 25 1,3812; ir (liquid 5.57μ (C=O); 19F nmr (CCl3F) δ 64.2 ppm (d, J = 173 Hz to d, J = 8 Hz, 1F), 65.7 ppm (d, J = 173 Hz to d, J = Hz, 1F) and 117.4 ppm (d, J = 10 Hz to d, J = 8 Hz, 1F).
