A chiral ferrocene-based bisphosphine ligand used extensively in homogeneous transition-metal catalysis. Commonly employed as a ligand for rhodium, iridium, palladium, ruthenium, nickel and copper catalysts in asymmetric hydrogenation, asymmetric allylic substitution, Suzuki-Miyaura coupling, Buchwald-Hartwig amination, Heck, Negishi and other cross-coupling reactions. Widely used in pharmaceutical intermediate synthesis, fine chemical production and asymmetric catalyst development.
