Participants

Reaction Steps

To prepare 2-trifluoromethyl-1,1,1,3,4,4,5,5,5-nonafluoro-2-pentanol, commercially available hexafluoropropene may be oligomerized with commercially available trimethylamine in a dipolar aprotic solvent such as commercially available tetrahydrofuran to provide (CF3)2C:CFCF2CF3 which is then reacted with commercially available hydrogen fluoride to yield 2-trifluoromethyl-1,1,1,3,3,4,4,5,5,5-decafluoropentane as taught by W. Brunskill et al., "Anionic Oligomerisation of Hexafluoropropene: Fission of a Carbon-Carbon Bond by Fluoride Ion", Chemical Communications, 1444 (1970). The 2-trifluoromethyl-1,1,1,3,3,4,4,5,5,5-decafluoropentane may then be dehydrohalogenated and then reacted with sulfuric acid and then water to form 2-trifluoromethyl-1,1,1,3,4,4,5,5,5-nonafluoro-2-pentanol.
