Description

(S)-(-)-5,5'-Dichloro-6,6'-dimethoxy-2,2'-bis(diphenylphosphino)-1,1'-biphenyl is a chiral bisphosphine ligand featuring electron-rich diphenylphosphino groups flanked by dichloro and dimethoxy substituents. This configuration enhances metal coordination stability in palladium-catalyzed cross-coupling reactions. The steric and electronic profile supports high catalytic efficiency under mild conditions.
