Used as a chiral ligand in asymmetric catalysis, particularly in transition-metal-catalyzed reactions such as asymmetric hydrogenation and cross-coupling reactions. Its rigid dinaphthyl backbone and phosphorus center with defined stereochemistry enable high enantioselectivity in the synthesis of pharmaceutical intermediates and fine chemicals. Commonly employed in the development of chiral catalysts for producing enantiomerically pure compounds, especially in the preparation of bioactive molecules where stereochemistry is critical. Its fluorinated aryl groups enhance electronic properties and binding affinity to metal centers, improving catalytic efficiency and selectivity.
