Baeyer-Villiger Type Oxidation in a Dioxygen-Arenecarbaldehyde-Ruthenium Dioxide or Manganese Dioxide System

Inokuchi, T.; Kanazaki, M.; Sugimoto, T.; Torii, S. Synlett 1994, 1037.

Aerobic Baeter-Villiger type reaction of cyclic ketones was achieved by using RuO₂, MnO₂, or other transition metal oxides as catalyst in the presence of arenecarbaldehyde, giving the corresponding lactones in good yields.
