General description
Trifluoromethanesulfonic anhydride, also known as triflic anhydride, is an electrophilic reagent that is an efficient source of trifluoromethyl. It is commonly used in organic chemistry to convert oxygen-containing compounds to triflates and for the electrophilic activation and subsequent conversion of amides, sulfoxides, and phosphorus oxides.
Application
Trifluoromethanesulfonic anhydride can be used as :
- A Reactant in the synthesis of Dipentaerythritol hexatriflate via triflatation method and Azido-diphenyl-acetic acid.
- Catalyst for glycosylation for synthesis of polysaccharides.
- Reagent for stereoselective synthesis of mannosazide methyl uronate donors.
- Activator for direct glycosylation with anomeric hydroxy sugars
- A methylation reagent to synthesize trifluoromethylated compounds by direct introduction of CF3 group to (hetero)arenes.
- A reagent to prepare substituted tetrazoles from secondary amides using sodium azide.
- A reagent in Bischler−Napieraiski cyclization reaction along with 4-(N,N-dimethylamnino)pyridine.
