    Description / Table of Contents: Dyotropic Rearrangements of Dinuclear μ-Aldehyde-zirconocene ComplexesIn solution dinuclear μ-aldehyde-zirconocene complexes 3a-h exhibit a dynamic behavior which shows features as being expected for a dyotropic rearrangement process. In view of the presumed structure of complexes 3 the remarkably low activation barriers of these thermally induced degenerate rearrangements, as determined by dynamic NMR spectroscopy (e.g. 3a: δG-129°C≠ = 7 kcal mol-1), could be interpreted to result primarily from a substantial ground state effect.
    Notes: Die zweikernigen μ-Aldehyd-zirconocen-Komplexe 3a-h zeigen in Lösung ein dynamisches Verhalten, das die erwarteten Eigenschaften einer dyotropen Umlagerung aufweist. Auf Grund der anzunehmenden Struktur der Komplexe 3 können die durch dynamische NMR-Spektroskopie bestimmten erstaunlich niedrigen Aktivierungsbarrieren dieser degenerierten thermischen Umlagerungen (z.B. 3a: δG-129°C≠ = 7 kcal mol-1) in erster Linie als Ausdruck eines ausgeprägten Grundzustandseffektes interpretiert werden.
