Organometall‐Imide – Höhervalente Derivate der d‐Metall‐Säuren, 1 Neue Organometall‐Imide des Molybdäns und Wolframs — die direkte Einführung der Cyclopentadienyl‐Gruppe durch Maskierung der hohen Oxidationsstufe

Organometallic Imido Complexes – Higher Valent Derivatives of the d‐Metal Acids, 1. – New Organometallic Imido Complexes of Molybdenum and Tungsten – Direct Introduction of the Cyclopentadienyl Group by Masking the High‐Oxidation State The molybdenum(VI)bis(tert‐butylimido) complex MO(NtBu)2‐Cl2 is converted into the novel organomolybdenum(VI) derivative (η5‐C5H5)MO(NtBu)2Cl (1) in excellent yield. The preparation of the pyridine complex W(NtBu)2Cl2py2 (2) provides a convenient starting material for an effective synthesis of the related complex (η5‐C5H5)W(NtBu)2Cl (4).
