Reaktionsschritte
As another example, 2-trifluoromethyl-1,1,1,3,3,4,4-heptafluoropentane may be prepared by fluorinating commercially available 2,3-pentanedione to form 2,2,3,3-tetrafluoropentane which may then be dehydrogenated to form 3,3,4,4-tetrafluoro-1-pentene. CF3 may then be added to the 3,3,4,4-tetrafluoro-1-pentene to form 2-trifluoromethyl-1,3,3,4,4-pentafluoropentane which may then be dehydrogenated to form 2-trifluoromethyl-1,3,3,4,4-pentafluoro-1-pentene. The 2-trifluoromethyl-1,3,3,4,4-pentafluoro-1-pentene may then be reacted with hydrogen fluoride to form 2-trifluoromethyl-1,1,3,3,4,4-hexafluoropentane which may then be dehydrogenated to form 2-trifluoromethyl-1,1,3,3,4,4-hexafluoro-1-pentene which may then be reacted with hydrogen fluoride to form 2-trifluoromethyl-1,1,1,3,3,4,4-heptafluoropentane.
