The oxidation of o-alkynylarenecarbaldehydes into tricarbonyl compounds by an iodine/watersystem is described. The reaction takes place via isochromenol intermediates formed by intramolecular assistance of the formylgroup. The procedure was applied to various o-alkynylarenecarbaldehydes to afford the corresponding products in good to excellent yields.
