    Description / Table of Contents: Zusammenfassung.  Die Synthese von neuen Ruthenium(II)-Komplexen, die zwei verschiedene chirale Liganden enthalten, wird beschrieben. Diese Liganden sind zum einen (−)-diop und zum anderen optisch aktive Imine, die aus der Kondensation von (S)-1-Phenylethylamin mit 2-Pyrrolaldehyd oder 2-Salicyladehyd stammen. Die Synthese beinhaltet die Darstellung der Vorstufen, die aus 1,5-Cyclooctadien (cod) und den entsprechenden Iminliganden bestehen. Obwohl für die oktaedrischen (−)-diop-Imin-Ruthenium(II)-Komplexe sechs Diastereomere möglich sind, wird in einer hoch stereoselektiven Reaktion jeweils nur ein Diastereomer gebildet.
    Notes: Summary.  The synthesis of novel ruthenium(II) complexes containing two different chiral ligands is described. These ligands are on the one-hand (−)-diop and on the other hand optically active imines derived from the condensation of (S)-1-phenylethylamine with 2-pyrrolealdehyde or 2-salicylaldehyde. The synthesis includes the preparation of the precursors containing 1,5-cyclooctadiene (cod) and the corresponding imine ligands. Although for the octahedral (−)-diop-imine-ruthenium(II) complexes six diastereomers are possible, in highly stereoselective reactions only one diastereomer is formed.
