Used as a chiral ligand in asymmetric catalysis, particularly in transition metal-catalyzed reactions where high enantioselectivity is required. Its rigid polycyclic structure and presence of sulfur and phosphorus atoms enable strong coordination to metals such as palladium, rhodium, or ruthenium, facilitating efficient stereocontrol in C–C bond-forming reactions. The perfluorophenylthio group enhances ligand stability and influences electronic properties, making it suitable for reactions under harsh conditions or in fluorinated solvent systems. Commonly applied in hydrogenation, allylic alkylation, and cross-coupling transformations in pharmaceutical and fine chemical synthesis.
