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.
