Abstract：(S)-2,2′-bis(diphenylphosphino)-1,1′-binaphthyl dioxide［（S）-2］ was obtained by oxidation， using H2O2 as the oxidant and (S)-2,2′-bis(diphenylphosphino)-1,1′-binaphthyl［(S)-1］ as the starting material. (S)-5,5′-dinitro-2,2′-bis(diphenylphosphino)-1,1′-binaphthyl dioxide［（S）-3］ was obtained by nitration of （S）-2 catalyzed by acidic resin. (S)-5,5′-diamino-2,2′-bis(diphenylphosphino)-1,1′-binaphthyl dioxide［（S）-4］ was obtained by hydrogenation reduction of ［（S）-3］ catalyzed by Pd/C. (S)-5,5′-diamino-2,2′-bis(diphenylphosphino)-1,1′-binaphthyl was synthesized by reduction of （S）-4 catalyzed by HSiCl3/PPh3. The total yield was 65.6%. The structures were confirmed by 1H NMR, 31P NMR and IR.
