Abstract

Dioxygen-tolerant [NiFe] hydrogenases catalyze not only the conversion of H2 into 2 H+ and 2 e- but also the reduction of O2 to H2O. Chemists have sought to mimic such bifunctional catalysts with structurally simpler compounds to facilitate analysis and improvement. Herein, we report a new [NiFe]-based catalyst for O2 reduction via an O2 adduct. Structural investigations reveal the first example of a side-on iron(IV) peroxo complex. Dioxygen-tolerant [NiFe] hydrogenases catalyze not only the conversion of H2 into 2 H+ and 2 e- but also the reduction of O2 to H2O. A new [NiFe]-based complex is a synthetic mimic of such hydrogenases and catalyzes O2 reduction via an O2 adduct, which was shown to be the first example of a side-on iron(IV) peroxo complex.
