Application

Trifluoromethanesulfonic acid can be used as a catalyst to prepare: Substituted tetrahydrofurans and tetrahydropyrans by cyclization of corresponding unsaturated alcohols under acidic conditions. Nitriles from corresponding aldehydes by Schmidt reaction. Disubstituted five-membered ring lactones by allylboration reaction between 2-alkoxycarbonyl allylboronates and aldehydes. It can also be used as a catalyst in the Fischer glycosylation and Friedel-Crafts acylation reactions.

General description

Trifluoromethanesulfonic acid is a strong organic acid. It can be prepared by reacting bis(trifluoromethylthio)mercury with H2O2. On mixing with HNO3, it affords a nitrating reagent (a nitronium salt). This reagent is useful for the nitration of aromatic compounds. Its dissociation in various organic solvents has been studied.
