Used as a chiral organocatalyst in asymmetric synthesis, particularly in enantioselective transformations where strong Brønsted acidity and well-defined chiral environment are required. Its perfluorinated aryl groups enhance acidity and stability, making it effective in catalyzing reactions such as asymmetric Friedel-Crafts alkylations, Mannich reactions, and transfer hydrogenations. The rigid binaphthyl backbone provides excellent stereocontrol, allowing high enantioselectivity in the synthesis of pharmaceuticals and fine chemicals. Solubility in fluorinated solvents also enables applications in biphasic and recyclable catalytic systems.
