Used as a chiral ligand in asymmetric catalysis, particularly in enantioselective hydrogenation and transfer hydrogenation reactions. Its rigid structure and electron-withdrawing trifluoromethyl groups enhance stereocontrol and catalyst efficiency. Commonly employed in the synthesis of pharmaceutical intermediates where high enantiomeric purity is required. Also utilized in coordination chemistry to form complexes with transition metals such as ruthenium, rhodium, and iridium for catalytic applications.
