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.

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.
