Widely used as a chiral ligand in asymmetric catalysis, this compound plays a key role in enantioselective transformations. It is particularly effective in palladium-catalyzed allylic substitution reactions, where it helps achieve high enantiomeric excess. Its ferrocene backbone provides structural rigidity and electronic tunability, enhancing stereocontrol. It is also employed in rhodium-catalyzed hydrogenation and other C–C bond-forming reactions, making it valuable in the synthesis of pharmaceuticals and fine chemicals where precise stereochemistry is required.
