Procedure

As another example, the 3-trifluoromethyl-2,2,4,4-tetrafluoropentane may be prepared by fluorinating commercially available 2,4-pentanedione to form 2,2,4,4-tetrafluoropentane which may then be dehydrohalogenated to form 2,4,4-trifluoro-2-pentene. The 2,4,4-trifluoro-2-pentene may then be reacted with CF3 to form 3-trifluoromethyl-2,2,4,4-tetrafluoropentane.
