Conclusions

  1. 1.

    The enantioselective activity of Raney cobalt catalysts obtained from cobalt-aluminum alloys with various compositions and modified by optically active tartaric acid and amino acids was investigated.

     
  2. 2.

    It was established that the optical yield during hydrogenation of ethyl acetoacetate at cobalt catalysts modified with amino acids bears an inverse relationship to the stability constants of the cobalt-amino acid complex.
