Lub ntsiab
(R) - (+) - 2,2-bis (diphenylphephino) -1,1-binaphthyl 丨 CAS 76189-55-4 yog ib qho ntawm feem ntau dav sivchiral nigandshauvasymmetric catalysisCov. Nws axial charcthyl kisab caj qaum, thiab dipherylphposphino hloov chaw muab ib qho zoo tshaj plaws ntawmChairality Tswj, Muaj peev xwm ua haujlwm, thiabTshuaj Muaj Peev XwmCov. Nws yog pob zeb nyob hauvenantioselective hydrogenation, yog dab neeg, thiabC-C raug khi ua keSiv cov hlau hloov.
