[1,1′-Binaphthalen]-2-yldi-tert-butylphosphine is a phosphine ligand featuring a binaphthyl backbone and two bulky tert-butyl groups attached to a phosphorus atom. This compound is widely used in organometallic chemistry and catalysis, particularly in asymmetric synthesis and cross-coupling reactions like Suzuki-Miyaura coupling. The steric hindrance provided by the tert-butyl groups and the rigid binaphthyl structure enhance its selectivity and stability in catalytic processes. It is valuable in the development of enantioselective reactions and fine chemical synthesis.
