Copper- or iron-catalyzed oxidative rearrangement of bicy- clo[n.1.0]alkan-1-ols yields 3-hydroperoxycycloalkanones and/or bicyclic peroxyhemiketals, which are transformed into 2,3-epoxy- cycloalkanones by treatment with a base.
Peroxidated compounds were prepared by treatment of ether solutions of bicyclo[n.1.0]alkanols with oxygen in the presence of silica gel, ferric acetylacetonate and light.
