説明Trifluoromethanesulfonic anhydride, also known as triflic anhydride, has proven to be an extraordinary reagent for a broad range of transformations. As a commercially and readily available reagent, It has been widely used in synthetic chemistry due to its high electrophilicity. Given its high affinity towards O-nucleophiles, reaction with alcohols, carbonyls, sulfur phosphorus- and iodine oxides towards the formation of the corresponding triflates is strongly favored. As one of the premier leaving groups in organic chemistry, the generated triflates then open the door to various downstream transformations, including (but not limited to) substitution reactions, cross-coupling processes, redox reactions, and rearrangements[1-2].
使用Trifluoromethanesulfonic Anhydride is a strong electrophile used in chemical synthesis for introducing the triflyl group.
純化方法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.]
