Beschreibung

Anwendung

Heptadecafluorooctanesulfonic acid solution can be used as a catalyst:

• In the benzoylation of a variety of unactivated benzenes via Friedel-Crafts acylation reaction in the presence of rare earth(III) perfluorooctane sulfonate in fluorous solvents.
• For the dinitration of aromatic compounds to synthesize dinitrobenzenes in the presence of ytterbium perfluorooctane sulfonate and fluorous solvent.
• To synthesize tetrahydroisoquinoline derivatives via Pictet-Spengler reaction of β-arylethyl carbamates with aldehydes.
