A novel system comprising metalloporphyrins and cyclohexene for the biomimetic aerobic oxidation of toluene

In this study, a novel system comprising metalloporphyrins and cyclohexene for the biomimetic aerobic oxidation of toluene and its derivatives was developed, which exhibited relatively benign reaction conditions, good catalytic activity, and broad substrate scope. Based on a series of in situ EPR (Electron Paramagnetic Resonance) and UV-vis experiments, the effect of cyclohexene on the reaction and the catalytic mechanism were preliminarily investigated.
