应用

Trifluoromethanesulfonic anhydride can be used in the preparation of azido sugars such as 6-azido fucose. It can also be used as a promoter for the Friedel-Crafts acylation of aromatic compounds with carboxylic acids in the absence of catalyst.
Tf2O in combination with:

  • Diphenyl sulfoxide, forms an efficient promoter system for the activation of thioglycosides for glycosylation reactions.
  • 2-chloropyridine, can be used for secondary amide activation.
  • Potassium iodide, can effectively mediate the deoxygenation of sulfoxides to form sulfides.
  • Hydrogen peroxide, for the selective oxidation of sulfanes to sulfoxides in the presence of oxidatively sensitive functional groups.

Tf2O can react with:
  • Ketones in the presence of a base to form vinyl triflates.
  • Magnesium alkoxides to form corresponding symmetrical or unsymmetrical ethers.
  • Sodium azide for thein situpreparation of triflyl azide.
