Two cycles : Based on a computational study, Co III OOR is put forward as the pivotal intermediate in the title reaction. Depending on the coordination environment of Co II , two very different catalytic cycles are accessible (see scheme). Irreversible catalyst deactivation takes place via the formation of an inactive dimer. Immobilization of cobalt on alumina results in a stable heterogeneous catalyst that is not subject to deactivation, since dimerization is prohibited.
