  • A chameleon catalyst for nonheme iron-promoted olefin oxidation CHEMICAL COMMUNICATIONS Iyer, S. R., Javadi, M. M., Feng, Y., Hyun, M. Y., Oloo, W. N., Kim, C., Que, L. 2014; 50 (89): 13777-13780


    We report the chameleonic reactivity of two nonheme iron catalysts for olefin oxidation with H2O2 that switch from nearly exclusive cis-dihydroxylation of electron-poor olefins to the exclusive epoxidation of electron-rich olefins upon addition of acetic acid. This switching suggests a common precursor to the nucleophilic oxidant proposed to Fe(III)-η(2)-OOH and electrophilic oxidant proposed to Fe(V)(O)(OAc), and reversible coordination of acetic acid as a switching pathway.
