    Description / Table of Contents: Synthesis of Mandelaldehydes by Catalytical Hydrogenation of Mandelonitriles over Raney Nickel in the Presence of Sulphuric AcidUnder strongly acid conditions it is possible with Raney nickel, to hydrogenate partially the aromatic cyanohydrins to mandelaldehydes. An improved method for the preparation of the cyanohydrins is described.
    Notes: Unter stark sauren Bedingungen gelingt es, aromatische Cyanhydrine mit Raney-Nickel partiell zu Mandelaldehyden zu hydrieren. Die Herstellung der Cyanhydrine wird verbessert.

    Description / Table of Contents: On the Course of the Catalytical Hydrogenation of Cinnamonitrile with Raney-Nickel in Presence of Sulfuric acidCinnamonitrile (1) can be hydrogenated selectively with Raney-Nickel in presence of concentrated sulfuric acid and, depending upon the solvent used, into the corresponding aldehyde 2 without attack at the C=C-bond.  -  With other solvents either 3-phenylpropanal (4) or 3-phenylpropanol (5) is formed.
    Notes: Zimtsäurenitril (1) läßt sich mit Raney-Nickel in Gegenwart konzentrierter Schwefelsäure und abhängig vom verwendeten organischen Lösungsmittel selektiv unter Erhalt der C=C-Bindung zum entsprechenden Aldehyd 2 hydrieren.  -  Mit anderen Lösungsmitteln entsteht entweder 3-Phenylpropanal (4) oder 3-Phenylpropanol (5).
