Applications
(^+)-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.

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

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