Reaction Steps

As another example, 4-trifluoromethyl-3,5,5,5-tetrafluoro-1-pentene may be prepared by fluorinating 3-pentanone to form 3,3-difluoropentane which may then be dehydrogenated to form 3,3-difluoro-1-pentene. CF3 may then be reacted with the 3,3-difluoro-1-pentene to form 2-trifluoromethyl-1,3,3-trifluoropentane which may then be dehydrogenated to form 2-trifluoromethyl-1,3,3-trifluoro-1-pentene. The 2-trifluoromethyl-1,3,3-trifluoro-1-pentene may then be reacted with hydrogen fluoride to form 2-trifluoromethyl-1,1,3,3-tetrafluoropentane which may then be dehydrogenated to form 2-trifluoromethyl-1,1,3,3-tetrafluoro-1-pentene which may then be reacted with hydrogen fluoride to form 2-trifluoromethyl-1,1,1,3,3-pentafluoropentane. The 2-trifluoromethyl-1,1,1,3,3-pentafluoropentane may then be dehydrohalogenated to form 4-trifluoromethyl-3,5,5,5-tetrafluoro-1-pentene.
