Butane, 1,1,1,4,4-pentafluoro-2-(trifluoromethyl)- → 3-Trifluoromethyl-1,4,4,4-tetrafluoro-1-butene

Participants

Reaction Steps

As another example, 3-trifluoromethyl-1,4,4,4-tetrafluoro-1-butene may be prepared by reacting commercially available 1,1-difluoroethylene according to the procedure of George L. Fleming et al., supra, to form a product which may then be hydrogenated to form 2-trifluoromethyl-1,1,1,2,4,4-hexafluorobutane which may then be dehydrohalogenated and then hydrogenated to from 2-trifluoromethyl-1,1,1,4,4-pentafluorobutane. The 2-trifluoromethyl-1,1,1,4,4-pentafluorobutane may then be dehydrohalogenated to form 3-trifluoromethyl-1,4,4,4-tetrafluoro-1-butene.
