BINAP Use and Manufacturing

racemic-2,2'-Bis(diphenylphosphino)-1,1'-binaphthyl ( (+/-)-BINAP ) is 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. used with Cu(II) to catalyze the addition of arylsulfonamides to styrenes and olefins.
