Trifluoromethanesulfonic Anhydride ke electrophile e matla e sebelisoang ho motsoako oa lik'hemik'hale bakeng sa ho hlahisa sehlopha sa triflyl.
Trifluoromethanesulfonic anhydride e sebelisoa ho fetolela phenols le ho imine ho triflic ester le sehlopha sa NTf. Ke electrophile e matla e sebelisetsoang ho kenyelletsa sehlopha sa triflyl ho motsoako oa lik'hemik'hale. E sebetsa e le reagent ha ho lokisoa li-alkyl le vinyl triflates, le bakeng sa motsoako oa stereoselective oa bafani ba mannosazide methyl uronate. E sebetsa e le sesosa sa glycosylation ka tsoekere ea anomeric hydroxy ho lokisa li-polysaccharides.
