Contributions to Organolanthanide Chemistry. II. On 2-(dimethylaminomethyl)ferrocenyl Compounds of Yttrium, Dysprosium, and HolmiumEarly reports about the ability of the 2-(dimethylaminomethy1)ferrocenyl group to form stable heterobimetallic organolanthanide(III) compounds have been confirmed by the synthesis of the organolanthanide(III) derivatives (C5H5)2Ln(FcN) [Ln = Y (II), Dy (III), Ho (IV)], C5H5Dy(FcN)2 · 2,5 THF (V) und C5H5Ln(FcN)Cl [Ln = Dy (VI), Ho (VII)] from the corresponding cyclopentadienyllanthanide(III) chlorides (C5H5)2LnCl or C5H5LnCl2 resp. and (FcN)Li (I). The products have been characterized by elemental analyses, IR-, 1H-NMR, 13C-NMR and UV/Vis spectra as well as mass spectra and the determination of their effective magnetic moments.
Notes:
Frühere Befunde, wonach 2-(Dimethylaminomethyl)ferrocenyl-Gruppen (FcN) zur Bildung stabiler, heterobimetallischer Organolanthanoid(III)-Verbindungen befähigt sind, wurden durch die Synthese der Organoseltenerd(III)-Derivate (C5H5)2SE(FcN) [SE = Y (II), Dy (III), Ho (IV)], C5H5Dy(FcN)2 · 2,5 THF (V) und C5H5SE(FcN)Cl [SE = Dy (VI), Ho (VII)] aus den betreffenden Cyclopentadienylseltenerd(III)-chloriden (C5H5)2SECl bzw. C5H5SECl2 und (FcN)Li (I) bestätigt. Die erhaltenen Verbindungen wurden durch Elementaranalysen, IR-, 1H-NMR-, 13C-NMR- und UV-Vis-Spektren sowie durch Bestimmung der effektiven magnetischen Momente und die Aufnahme von Massenspektren charakterisiert.
