A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 4488-22-6, Name is [1,1′-Binaphthalene]-2,2′-diamine, molecular formula is C20H16N2. In a Patent，once mentioned of 4488-22-6, Application In Synthesis of [1,1′-Binaphthalene]-2,2′-diamine
This invention relates to (R)- and (S)-5,5′,6,6′,7,7′,8,8′-octahydro-1,1′-binaphthyl-2,2′-diamine (R-1 and S-1) and (R)- and (S)-2,2′-bis(diarylphospinoamino)-5,5′,6,6′,7,7′,8,8′-octahydro-1,1′-binaphthyl (R-2 and S-2) and (R)- and (S)-2,2′-bis(dialkylphospinoamino)-5,5′,6,6′,7,7′,8,8′-octahydro-1,1′-binaphthyl (R-3 and S-3); to a process for the preparation of R-1 and S-1 in which (R) or (S)-1,1′-binaphthyl-2,2′-diamine is partially hydrogenated in the presence of Adam’s catalyst (5-20 wt % of starting material) at 20-100 C. for 20-100 hours in glacial acetic acid (solvent); to a process for the preparation of R-2, S-2, R-3 and S-3 in which R-1 or S-1 is reacted with chlorodiarylphosphine or chlorodialkylphosphine in the presence of n-butyllithium; and to the rhodium complexes containing 2 or 3 as effective catalysts for the asymmetric hydrogenation of prochiral substrates such as olefins to produce higher valued chiral products; and to the asymmetric catalytic hydrogenation of enamides under mild conditions using the Rh-(2) or Rh-(3) as catalyst with chemical yields as high as 100% and enantiomeric excess (e.e.) as high as 99%.
