HCID 197812312-Methyl-1,2,3,3,4,4-hexafluorobutane

Procedure

As another example, 2-methyl-4-chloro-1,1,2,3,3,4,4-heptafluorobutane may be prepared by fluorinating commercially available 2-methyl-1-buten-3-yne to form 2-methyl-1,2,3,3,4,4-hexafluorobutane which may then be dehydrohalogenated to form 2-methyl-1,3,4,4-tetrafluoro-1,3-butadiene. The 2-methyl-1,3,4,4-tetrafluoro-1,3-butadiene may then be chlorofluorinated to form 2-methyl-4-chloro-1,1,2,3,3,4,4-heptafluorobutane.
