(-)-1,2-Bis((2R,5R)-2,5-diphenylphospholano)ethane（Cat No.:L023089）is a chiral bidentate diphosphine ligand commonly used in asymmetric catalysis. Featuring two (2R,5R)-2,5-diphenylphospholane rings connected by an ethane linker, it offers a rigid and stereochemically defined framework ideal for enantioselective transformations. This ligand is especially effective in transition metal-catalyzed reactions such as hydrogenation, hydroformylation, and cross-coupling, providing high enantioselectivity and catalytic efficiency. Its well-defined geometry and strong metal coordination ability make it a valuable tool in both academic and industrial synthesis of chiral molecules, including active pharmaceutical ingredients and fine chemicals.
