In a manner similar to Step A of Example 1, the reaction of 26.0 g (0.25 mole) 2,6-dichlorothiophenol, 20.0 g (0.15 mole) potassium carbonate and 75.4 g (0.30 mole) 1,2-dibromotetrafluoroethane in 200 ml of N,N-dimethylformamide produced 31.5 g of 2-(2-bromo-1,1,2,2-tetrafluoroethylthio)-1,3-dichlorobenzene as an oil. The nmr and ir spectra were consistent with the proposed structure.
