Insights into the Cobalt(II)-Catalyzed Decomposition of Peroxide

Two cycles: Based on a computational study, CoIIIOOR is put forward as the pivotal intermediate in the title reaction. Depending on the coordination environment of CoII, 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.
