Trifluoromethanesulfonic anhydride Chemical Properties,Uses,Production

Chemical Properties

clear colorless to light brown liquid

Uses

Trifluoromethanesulfonic Anhydride is a strong electrophile used in chemical synthesis for introducing the triflyl group.

Purification Methods

It 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. J Chem Soc 2574 1957, Beard et al. J Org Chem 38 373 1973, Beilstein 3 IV 35.]
