Application

Ba(CF3SO3) can be utilized as a precursor to synthesize:
  • Alkali metal and silver trifluoromethanesulfonates.
  • Sodium trifluoromethanesulfonate (sodium triflate) by reacting with sodium sulfate. Sodium triflate finds application in organic synthesis as an efficient catalyst as well as a reactant in catalytic asymmetric Mannich-type reactions, and Diels-Alder reactions.
