Description

Pyridinium trifluoromethanesulfonate delivers a robust, moisture-tolerant source of triflic acid under mild conditions. This bench-stable salt features a pyridinium cation paired with a highly stable triflate anion, enabling efficient proton transfer in synthetic transformations. It integrates seamlessly into catalytic systems requiring strong yet controllable acidity, particularly in C–H functionalization and esterification reactions.

Application

Pyridinium trifluoromethanesulfonate serves as a highly effective catalyst for acid-promoted transformations, enabling efficient O- and N-arylations, glycosylations, and deprotection reactions under mild conditions. Its bench-stable solid form facilitates handling, while the triflate anion ensures high catalytic activity with excellent functional group tolerance across diverse synthetic workflows.
