Widely used as a bidentate phosphine ligand in homogeneous catalysis, particularly in palladium-catalyzed cross-coupling reactions. Its steric bulk and electron-rich nature enhance catalytic activity and stability in transformations such as Suzuki, Heck, and Negishi couplings. The ferrocene backbone provides structural rigidity and redox activity, which can be exploited in electrochemical applications and sensors. It is also employed in asymmetric synthesis when paired with chiral metals, facilitating enantioselective C–C and C–heteroatom bond formations. Due to its solubility in organic solvents, it is well-suited for use in solution-phase catalytic systems.
