Triflic anhydride may be used to introduce a protective trifluoromethane sulfonyl group. It is a strong activator of hydroxyl groups, for example in glycosidation reactions. It is an efficient promoter for inversion configuration and for nucleophilic substitutions. It may also be used as an activator of phenols or enols for the synthesis of aryl and vinyl triflates.
