A chiral ferrocene-based bisphosphine ligand extensively used in homogeneous transition-metal catalysis. Commonly employed as a ligand for rhodium, iridium, palladium, nickel, ruthenium and copper catalysts in asymmetric hydrogenation, asymmetric allylic substitution, C-C and C-N cross-coupling reactions, hydroboration, hydroformylation, and the synthesis of pharmaceutical intermediates and fine chemicals. Particularly suitable for highly enantioselective catalytic transformations.
