Description	Trifluoromethanesulfonic anhydride, also known as triflic anhydride, is an electrophilic reagent that is an efficient source of trifluoromethyl.
Hazard	May be corrosive to metals. Harmful if swallowed. Causes severe skin burns and eye damage.
Flammability and Explosibility	Notclassified
storage	Store in a cool, dry, wellventilated area. ?Moisture sensitive.
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.

An unprecedented application of trifluoromethanesulfonic anhydride as a radical trifluoromethylation reagent was developed by merging photoredox catalysis and pyridine activation. The synthetic utility of this method is exemplified by the C−H trifluoromethylation of (hetero)arenes and trifluoromethyltriflation of alkynes.

Trifluoromethanesulfonic anhydride has been widely used in synthetic organic chemistry, not only for the conversion of various oxygen-containing compounds to the triflates, but also for the electrophilic activation and further conversion of amides, sulfoxides, and phosphorus oxides. In recent years, the utilization of Tf2O as an activator for nitrogen-containing heterocycles, nitriles and nitro groups has become a promising tool for the development of new valuable methods with considerable success.
