実験手順
Using the method described in Example 3, 3-methyl-2-butanone was reacted with trifluoromethanesulfenyl chloride to provide a reaction product which was distilled. The product had a boiling point of 51° to 84°C/48 mm. Vapor phase chromatography of this distillate showed two products to be present in major quantities. Fractional distillation of this product provided 3-trifluoromethylthio-3-methyl-2-butanone, b.p. 68°C/54 mm Hg and 1-trifluoromethylthio-3-methyl-2-butanone, b.p. 84°C/54 mm Hg. The structures of these compounds were determined by spectral and elemental analyses.
