2,2'-Bis(dicyclopentylphosphino)-1,1'-binaphthyl und Metallkomplexe davon. |
摘要 |
<p>2,2 min -bis(dicyclopentylphosphino)-1,1 min -binaphthyl is prepared by the reactions: <CHEM> The optical resolution of the racemic (IX) is effected by adding an ethyl acetate solution, of (+) or (-) dibenzoyltartaric acid, recrystallisation, solution in chloroform, adding NaOH, distillation and recrystallisation. The product (I) forms a complex with a transition metal, e.g. Rh, Pd, Ru, Ir or Ni, and the complexes are useful as catalysts, e.g. for asymmetric hydrogenation, giving high yields.</p> |
