This chemical is primarily used as a chiral ligand in asymmetric catalysis, particularly in transition metal-catalyzed reactions. It plays a critical role in facilitating enantioselective transformations, such as hydrogenation, cross-coupling, and allylic substitution reactions. Its structure, featuring a dicyclohexylphosphine group and a sulfinamide moiety, allows for precise control over stereochemistry, making it valuable in the synthesis of chiral intermediates for pharmaceuticals and fine chemicals. Additionally, its stability and selectivity make it a preferred choice in research and industrial applications where high enantiomeric purity is essential.
