実験手順

A mixture of 17.6 g (0.10 mol) of trifluoromethylmalonyl fluoride (containing ca. 5% of the ketene) and 24 g (0.3 mol) of SO3 was heated and crude distillate was redistilled to provide 11.9 g (40%) of pyrosulfuryl fluoride, bp 51°-54°C, and 2.4 g (15%) of trifluoromethylfluorocarbonylketene, bp 58°-59.5°C. Pyrosulfuryl fluoride was identified by comparison of bp, infrared spectrum and nmr spectrum with those reported for authentic samples. The ketene was shown in infrared to be the same as that prepared in Example 4.
