(+/-)-2,2'-双(二苯基膦基)-1,1'-联萘

(^+)-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.
