Application

(R)-ECNU-Phos is a versatile chiral ligand employed in asymmetric hydrogenation, C-C bond formation, and other transition-metal-catalyzed reactions. Its electron-rich phosphine groups and rigid biphenyl backbone make it particularly effective for enantioselective synthesis of pharmaceuticals and fine chemicals. Researchers value this ligand for its high stereocontrol and compatibility with a wide range of metal catalysts, including rhodium and ruthenium complexes.
