A chiral ferrocenyl phosphine-oxazoline (PHOX) ligand widely used in asymmetric catalysis. Commonly employed as a ligand for palladium, iridium, rhodium, ruthenium, and copper catalysts in asymmetric allylic substitution, hydrogenation, conjugate addition, cyclization, and other enantioselective transformations. Frequently utilized in pharmaceutical research, fine chemical synthesis, and catalyst development.
