Chemistry Organocatalysts NHTf

NHTf

NHTf, short for triflimide (bis(trifluoromethanesulfonyl)imide), is a strong Brønsted acid frequently used as a catalyst or counterion in organic synthesis. As an achiral, non-nucleophilic acid, NHTf is valued for its high acidity and its ability to promote a wide range of electrophilic transformations under mild conditions. It often serves as a co-catalyst in combination with chiral ligands or metal complexes in enantioselective reactions such as allylations, acetalizations, and C–H activations. Additionally, triflimide is commonly used as a counterion in ionic liquids and phase-transfer catalysts, enhancing the solubility and stability of reactive intermediates. In organocatalysis, it facilitates key steps such as iminium formation and carbocation stabilization. Its exceptional thermal and chemical stability also makes NHTf a versatile additive in polymerizations and electrochemical processes. While not inherently chiral, it plays an essential role in modern catalysis by enhancing the activity and selectivity of chiral catalyst systems.
