Procedure

Using the method of Example 3, 2-butanone was reacted with trifluoromethanesulfenyl chloride. The reaction mixture was distilled, b.p. 30°-72°C/55 to 60 mm. Vapor phase chromatography of the distillate showed two products to be present in major quantities. Fractional distillation gave 3-trifluoromethylthio-2-butanone, b.p. 66°C/62 mm Hg, and 1-trifluoromethylthio-2-butanone, b.p. 85°C/62 mm Hg. These structures were established by spectral and elemental analyses.
