 Title    Optisch aktive Übergangsmetall-Komplexe  
 Abstract    , LV [1]. Darstellung und Stereochemie von [C5H5Mo(CO)2 NN'jPFe mit NTS'=Ethylen-diamin und Propylendiamin Optically Active Transition Metal Complexes, LV [1] Preparation und Stereochemistry of [C5H5Mo(CO)2NN']PF6 with NN'=Ethylenediamine and Propylene -diamine In the reaction of CsHsMotCO^Cl with ethylenediamine and propylenediamine, ab-breviated with NN', the square pyramidal cations [C5H5Mo(C0)2NN'] + are formed. The diastereoisomeric pairs of enantiomers of the propylenediamine derivative are separated by fractional crystallization. The epimerization at the asymmetric Mo atom (n,2 = 30 min, 75 °C, CD3OD solution) can be followed by NMR spectroscopy.
