    Description / Table of Contents: Regioselectivity and Steric Course of Lewis Acid Promoted Ring Enlargement of Cyclohexadiene Complexes with Carbon MonoxideTreating the tricarbonyliron complexes 5 and 7 of substituted cyclohexadienes with AlCl3 yields complexes 6, 8, and 9 of seven-membered ring ketones, containing carbon monoxide inserted into one of the double bonds with high regioselectivity depending on the substitution pattern. The mechanism of this ring enlargement is discussed, and an X-ray analysis of 8e is carried out.
    Notes: Durch Behandeln der Tricarbonyleisen-Komplexe 5 und 7 substituierter Cyclohexadiene mit AlCl3 entstehen die Komplexe 6, 8 und 9 von Siebenringketonen, in denen Kohlenmonoxid in Abhängigkeit vom Substitutionsmuster mit hoher Regioselektivität in eine der Doppelbindungen eingeschoben ist. Der Mechanismus dieser Ringerweiterung wird diskutiert, und von 8e wird eine Röntgenstrukturanalyse ausgeführt.
