A chiral Josiphos-type ferrocenyl bisphosphine ligand widely used in homogeneous asymmetric catalysis. Commonly coordinated with rhodium, iridium, palladium, ruthenium, nickel and copper catalysts for asymmetric hydrogenation, allylic substitution, cross-coupling, hydroboration, conjugate addition and other enantioselective transformations. Frequently employed in pharmaceutical process development, fine chemical synthesis and catalyst research.
