2,2'-bis(diphenylphosphanyl)-1,1'-binaphthalene; CAS No.: 98327-87-8; 2,2'-bis(diphenylphosphanyl)-1,1'-binaphthalene. PROPERTIES: This phosphorus-substituted binaphthalene features molecular formula C??H??P? with molecular weight 470.51 g/mol. Exists as a white powder. Soluble in non-polar solvents like hexanes and dichloromethane. Melting point approximately 180-185 C. Exhibits IR absorption for P-C bonds. Thermogravimetric analysis indicates decomposition above 250 C under nitrogen. Store at 2-8 C in sealed containers. May cause skin irritation and eye damage. APPLICATIONS: As a chiral phosphane ligand, 2,2'-bis(diphenylphosphanyl)-1,1'-binaphthalene is used in transition metal catalysis. It serves as key intermediate in asymmetric hydrogenation reactions to form chiral amines. Also used in materials science as monomer for preparing polyphosphane membranes with enhanced gas separation properties.
