应用
Trifluoromethanesulfonic anhydride is used to convert phenols and imine into triflic ester and NTf group. It is a strong electrophile used for the introduction of triflyl group in chemical synthesis. It serves as a reagent in the preparation of alkyl and vinyl triflates, and for the stereoselective synthesis of mannosazide methyl uronate donors. It acts as a catalyst for glycosylation with anomeric hydroxy sugars to prepare polysaccharides.

备注
Moisture sensitive. Incompatible with water, strong bases, strong oxidizing agents, acids and alcohols.

产品说明

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 the in situ preparation of triflyl azide.
