R(+)-2,2′-Bis(diphenylphosphino)-6,6′-dimethoxybiphenyl (Cat No.: M117648), often abbreviated as (R)-BINAP-OMe, is a chiral diphosphine ligand derived from the BINAP framework, featuring methoxy substitutions at the 6,6′-positions. It is widely used in asymmetric catalysis, particularly in transition-metal-catalyzed hydrogenation and cross-coupling reactions. The rigid, atropisomeric biphenyl backbone provides high enantioselectivity, making it a valuable tool in enantioselective synthesis. Its electronic and steric properties can be fine-tuned for specific catalytic systems, making it indispensable in pharmaceutical and fine chemical development.
