Used as a chiral ligand in asymmetric catalysis, particularly in transition-metal-catalyzed reactions such as asymmetric hydrogenation and cross-coupling reactions. Its phosphine and sulfinamide functional groups coordinate effectively with metals like palladium, rhodium, and ruthenium, enabling high enantioselectivity in the synthesis of chiral molecules. Commonly employed in pharmaceutical and fine chemical industries for the production of enantiomerically pure compounds. The steric bulk and electronic properties of the ligand framework enhance catalytic efficiency and stereochemical control.
