Used as a chiral ligand in asymmetric catalysis, particularly in transition-metal-catalyzed reactions such as asymmetric hydrogenation and C–C bond formation. Its rigid, sterically hindered structure enhances enantioselectivity, making it valuable in the synthesis of optically active pharmaceuticals and fine chemicals. The phosphorus center coordinates with metals like rhodium, ruthenium, or palladium, forming catalytically active complexes that deliver high stereochemical control. Commonly applied in academic and industrial research for developing enantioselective processes.
