This chemical is primarily used as a chiral ligand in asymmetric catalysis, particularly in transition metal-catalyzed reactions. Its structure, featuring a dicyclohexylphosphine group and a sulfinamide moiety, makes it highly effective in inducing enantioselectivity in various organic transformations. It is often employed in the synthesis of pharmaceuticals and fine chemicals, where the production of a single enantiomer is crucial for biological activity or desired properties. Additionally, it is utilized in the development of novel catalytic processes for the creation of complex molecular architectures with high precision and efficiency.
