Used as a chiral ligand in asymmetric catalysis, particularly in enantioselective transformations such as hydrogenation, cross-coupling, and C–H activation reactions. Its sterically bulky structure and well-defined chiral environment enhance selectivity and stability of metal catalysts, especially with rhodium, ruthenium, and palladium. Commonly employed in the synthesis of pharmaceuticals and fine chemicals where high enantiomeric purity is required. The ligand’s rigidity and electron-rich phosphine groups facilitate efficient turnover and improved yield in asymmetric synthesis.
