Used as a chiral ligand in asymmetric catalysis, particularly in transition-metal-catalyzed reactions such as asymmetric hydrogenation and cross-coupling reactions. Its rigid dinaphtho backbone and phosphorus center with defined stereochemistry enable high enantioselectivity in the synthesis of chiral molecules. Commonly employed in pharmaceutical and fine chemical industries to produce enantiomerically pure compounds. The presence of fluorinated aryl groups enhances ligand stability and influences electronic properties, improving catalytic efficiency. Suitable for use with palladium, rhodium, and ruthenium complexes.
