Trifluoromethanesulfonic anhydride Usage And Synthesis
Chemical Propertiesclear colorless to light brown liquid
UsesTrifluoromethanesulfonic Anhydride is a strong electrophile used in chemical synthesis for introducing the triflyl group.
UsesTrifluoromethanesulfonic 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.
Purification MethodsIt can be freshly prepared from the anhydrous acid (11.5g) and P2O5 (11.5g, or half this weight) by setting aside at room temperature for 1hour, distilling off volatile products then distil it through a short Vigreux column. It is readily hydrolysed by H2O and decomposes appreciably after a few days to liberate SO2 and produce a viscous liquid. Store it dry at low temperatures. [Burdon et al.
