Reaction equation
[F:1][C:2]([F:12])([F:11])[C:3]([C:6]([F:10])([F:9])[CH2:7][CH3:8])=[CH:4][F:5].[FH:13]>>[F:1][C:2]([F:11])([F:12])[CH:3]([C:6]([F:9])([F:10])[CH2:7][CH3:8])[CH:4]([F:13])[F:5]Participants
Procedure
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.
