Trifluoromethanesulfonic acid difluoromethyl ester Usage And Synthesis
UsesDifluoromethyl triflate (TfO-CHF2) can be used as a reagent:
  • In difluoromethylation reaction.
  • To prepare difluoromethoxylated heterocycles by reacting with hydroxylated N-based heterocycles.
  • To synthesize trifluoromethylated arenes by treating with diaryliodonium salts in the presence of copper and tetrabutylammonium difluorotriphenylsilicate (TBAT).

It allows for a simple method toward the preparation of difluoromethyl ethers and thioethers under basic conditions from alcohols and thiols. Difluoromethyl phenols can also be obtained in a single pot from boronic acids and C-H activation of arenes.
General DescriptionDifluoromethyl triflate (HCF2OTf) is an easy to handle, air-stable and non-ozone-depleting liquid reagent for difluoromethylation. It can be prepared by reacting trifluoromethyltrimethylsilane (TMSCF3) and triflic acid in the presence of titanium tetrachloride (TiCl4).
