Abstract
The first lactam-type 2-iodobenzamide catalysts, 8-iodoisoquinolinones 8 (IB-lactam) and 9 (MeO-IB-lactam), were developed. These catalysts have a conformationally rigid 6/6 bicyclic lactam structure and are more reactive than the previously reported catalysts 2-iodobenzamides 4 (IBamide) and 5 (MeO-IBamide) for the oxidation of alcohols. The lactam structure could form an efficient intramolecular I---O interaction, depending on the size of the lactam ring.
