Used as a specialized bidentate ligand in homogeneous catalysis, particularly in palladium-catalyzed cross-coupling reactions. Its rigid backbone and electron-rich phosphine groups enhance catalytic activity and stability, improving selectivity and yield in transformations such as Suzuki–Miyaura and Buchwald–Hartwig aminations. Effective in promoting challenging carbon–carbon and carbon–heteroatom bond formations, especially in sterically hindered or electronically deactivated substrates. Also applied in asymmetric synthesis when coordinated to chiral metal complexes, enabling enantioselective catalysis in pharmaceutical and fine chemical manufacturing.
