Common Chiral Biphylphosphine Ligands – BINAP
R-BINAP, R-(+)-2,2′-bis(diphenylphosphino)-1,1′-binaphthyl 【(R)-(+)-2,2′-Bis(diphenylphosphino)-1,1′-binaphthyl】 【CAS Number】76189-55-4 【Appearance】White powder S-BINAP, S-(-)-2,2′-bis(diphenylphosphino)-1,1′-binaphthyl 【(S)-(-)-2,2′-Bis(diphenylphosphino)-1,1′-binaphthyl】 【CAS Number】76189-56-5 【Appearance】White powder In 1980, Noyori first synthesized BINAP and used it in chiral catalysis, demonstrating excellent enantioselectivity. Subsequently, BINAP and various metal (Ru, Pd, Ag, Rh, Ir, Au) complexes were continuously used in various reactions. Asymmetric hydrogenation reactions reduced aldehydes and ketones, used … Read more
