Description

General description

Sodium trifluoromethanesulfonate (Sodium triflate or NaOTf) is an efficient catalyst as well as a reagent in many organic reactions. The prominent application includes catalytic asymmetric Mannich-type reactions, Mannich-type reactions in water, and Diels-Alder reactions.It is also used as an electrolyte in batteries.

Application

Sodium trifluoromethanesulfonate can be employed as a reagent for the preparation of:

• Aryl fluorides via silver-catalyzed fluorination of arylstannanes.
• Ionic liquids such as N, N -dialkylpyrrolidinium triflate, N,N-dialkylimidazolium triflate, and N-alkylpyridinium triflate.

It can be also used as supporting electrolyte in electrochemical O-glycosylation of primary alcohols with O-protected thioglycosides.
