Versuchsvorschrift

To a mixture of 600 mg of 3,5-dichloro-4-(1,1,2,2-tetrafluoroethoxy)phenol, 330 mg of potassium carbonate and 10 ml of N,N-dimethylformamide was added dropwise a solution of 340 mg of 1,1,3-trichloro-1-propene dissolved in 3 ml of N,N-dimethylformamide, while stirring at room temperature. After stirring continued at room temperature for 5 hours, the reaction mixture was poured into ice-water, and extracted twice with 40 ml of diethyl ether. The combined ether layer was washed with water, dried with anhydrous magnesium sulfate, and concentrated to obtain a crude product. The crude product was subjected to silica gel chromatography, which afforded 630 mg of 3,5-dichloro-4-(1,1,2,2-tetrafluoroethoxy)-1-(3,3-dichloro-2-propenyloxy)benzene (82% yield), nD24.6 1.5067.
