BeschreibungTrifluoromethanesulfonic 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].

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