Cas no 145416-77-9 (rac-2,2 -Bis(di(3,5-dimethylphenyl)phosphino)-1,1 -binaphthyl)

Technical Introduction: rac-2,2'-Bis(di(3,5-dimethylphenyl)phosphino)-1,1'-binaphthyl is a chiral bidentate phosphine ligand featuring a binaphthyl backbone substituted with sterically demanding 3,5-dimethylphenyl groups on the phosphorus atoms. This structural design enhances its utility in asymmetric catalysis, particularly in transition-metal-catalyzed reactions such as hydrogenations and cross-couplings. The electron-rich and sterically hindered phosphine moieties contribute to high enantioselectivity and reactivity, while the rigid binaphthyl framework ensures stability under demanding conditions. Its racemic form is valuable for screening and optimizing catalytic systems. The ligand is typically employed in homogeneous catalysis, offering predictable performance in stereocontrolled transformations.
