- Overview
  - Trifluoromethanesulfonic anhydride is more frequently known as triflic anhydride, since it derives from triflic acid. It is a versatile and strong electrophile used to insert the triflyl group (represented as Tf-) into chemical molecules (Ouyang, 2018). For example, trifluoromethane sulfonic anhydride interacts with some alkylsulfides to form stable salts that are used in the oxidation of alcohols. Moreover, trifluoromethane sulfonic anhydride has successfully shown high activity as a promoter in glycosylation reactions to obtain disaccharides (Tatai, 2007).
