Soluble in tetrahydrofuran, benzene and dichloromethane. Slightly soluble in ether, methanol and ethanol. Insoluble in water.


(^+)-2,2'-Bis(diphenylphosphino)-1,1'-binaphthyl plays an essential role in the organic synthesis of enantioselective transformations catalyzed by the complexes of ruthenium, rhodium and palladium. It is also employed in palladium-catalyzed arylamine coupling in the preparation of demethylthiocholchines. It is used with Cu(II) to catalyze the addition of arylsulfonamides to styrenes and olefins.


Air sensitive. Keep container tightly closed in a dry and well-ventilated place.
