Trifluoroethanol serves as a solvent and a raw material in organic chemistry and biology. TFE is a solvent of choice for hydrogen peroxide-mediated oxidations of sulfides. Trifluoroethanol acts as a protein denaturant. It is used in the manufacture of certain pharmaceuticals and drug substances. The drug fluromer, which is 2,2,2-trifluoro-1-vinyloxyethane, is the vinyl ether of trifluorethanol. It is an effective solvent for peptides and proteins, and used for NMR-based protein folding studies, and in the manufacture of nylon. As a source of the trifluoromethyl group, it is employed in several organic reactions, for example in Still-Gennari modification of Horner-Wadsworth-Emmons reaction (HWE) reaction.
Useful ionizing solvent, see: Tetrahedron Lett., 2335 (1974), and references therein. Good solvent for oligopeptides with potential as a cosolvent along with proton acceptors such as DMF for peptide coupling reactions: Tetrahedron Lett., 33, 7007 (1992). Compare 1,1,1,3,3,3-Hexafluoro-2-propanol, A12747.
Effective solvent for uncatalyzed epoxidations of alkenes with hydrogen peroxide (caution! 60%): Synlett, 248 (2001). For a review of fluorinated alcohols as solvents for selective and clean reactions, see: Synlett, 18 (2004).
Trifluoroethyl esters have also found use as active esters in peptide coupling; see, for example: J. Chem. Soc., Perkin 1, 2867 (1996).
Reacts with triphenylphosphine dibromide to give the bis(trifluoroethoxy)phosphorane, which converts alcohols to trifluoroethyl ethers, carboxylic acids to trifluoroethyl esters and aldehydes to bis(trifluoroethyl) acetals: J. Org. Chem., 45, 5052 (1980).
The stereodirecting effect of the MEM group (see 2-Methoxyethoxymethyl chloride, L01050) has been exploited by Percy et al in the formation of a new fluorine-containing acyl anion equivalent: Tetrahedron, 51, 9201 (1995):
Claisen or Wittig rearrangements of the derived difluoroallyl alcohols can be used in routes to molecules containing a CF2 group: Tetrahedron, 51, 11327 (1995); J. Org. Chem., 61, 166 (1996), or to monofluorinated vinylic compounds: Tetrahedron Lett., 37, 5183 (1996).
