| Description | [(salen)Fe^{III}]^{+}$_{MeCN}$ complex is a useful catalyst for cyclohexene oxidation with dioxygen. As the main products, ketone and alcohol are formed. In acetonitrile, [(salen)Fe^{II}$]_{MeCN}$ is rapidly oxidized by dioxygen, forming iron(III) species. Voltammetric electroreduction of the [(salen)Fe^{III}]^{+}$_{MeCN}$ complex in the presence of dioxygen causes the increase in current observed, which indicates the existence of a catalytic effect. Further transformations of the oxygen-activated iron(III) salen complex generate an effective catalyst. Based on the catalytic and electrochemical results, as well as DFT calculations, possible forms of active species in $c-C_{6}H_{10}$ oxidation have been proposed. |
