Application
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.
Reagent for stereoselective synthesis of mannosazide methyl uronate donors
Activator for direct glycosylation with anomeric hydroxy sugars
