Used as a chiral bidentate ligand in asymmetric catalysis, particularly in transition metal-catalyzed reactions such as hydrogenation, allylic alkylation, and cross-coupling transformations. Its sterically hindered, electron-rich phosphine groups enhance enantioselectivity and catalytic efficiency. Commonly employed with rhodium, ruthenium, or palladium complexes to achieve high stereochemical control in the synthesis of pharmaceuticals and fine chemicals. The rigid chiral backbone ensures well-defined coordination geometry, making it valuable in producing enantiopure compounds.
