Abstract

Carbonyl compounds react with trifluoromethanesulfonic (triflic) anhydride to give products of different structure and stereochemistry. Ketones afford vinyl trifluoromethanesulfonates (triflates), while gem-ditriflates have been isolated from aldehydes and nonenolizable ketones.'Triflates have been found to be valuable starting
