摘要
Dioxygen-tolerant [NiFe] hydrogenases catalyze not only the conversion of H-2 into 2H(+) and 2e(-) but also the reduction of O-2 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 O-2 reduction via an O-2 adduct. Structural investigations reveal the first example of a side-on iron(IV) peroxo complex.
