1,1,1,3,3-Pentachloro-2-propanone → Pentafluoroacetone

Participants

Reaction Steps

As another preparation example, 2-difluoromethyl-1,1,1,3,3-pentafluoro-2-propanol may be prepared by fluorinating commercially available 1,1,1,3,3-pentachloro-2-propanone to form 1,1,1,3,3-pentafluoro-2-propanone which may then be reacted with CF2 carbene to form 2-difluoromethyl-1,1,3,3,3-tetrafluoro-1-propene. The 2-difluoromethyl-1,1,3,3,3-tetrafluoro-1-propene may then be reacted with sulfuric acid and then water to form 2-difluoromethyl-1,1,1,3,3-pentafluoro-2-propanol.
