A longstanding research goal has been to understand the nature and role of copper–oxygen
intermediates within copper-containing enzymes and abiological catalysts. Synthetic …

Methane monooxygenases (MMOs) mediate the facile conversion of methane into methanol
in methanotrophic bacteria with high efficiency under ambient conditions. Because the …

Nature uses dioxygen as a key oxidant in the transformation of biomolecules. Among the
enzymes that are utilized for these reactions are copper-containing metalloenzymes, which …

A long-standing debate in the Cu–O 2 field has revolved around the relevance of the Cu (III)
oxidation state in biological redox processes. The proposal of Cu (III) in biology is generally …

Moving towards a hydrogen economy raises the demand for affordable and efficient
catalysts for the oxygen reduction reaction. Cu-bmpa (bmpa= bis (2-picolyl) amine) is shown …

Tris-copper centers are present at the active site of multicopper oxidases (MCO) which
couple the four-electron reduction of molecular oxygen to water with the oxidation of …

Ubiquitous copper-oxygen species are pivotal in enabling multifarious oxidation reactions in
biological and chemical transformations. We herein construct a macrocycle-protected mixed …

The scission of the O–O bond in O2 during respiration and the formation of the O–O bond
during photosynthesis are the engines of aerobic life. Likewise, the reduction of O2 and the …

We report that exposing the dipyrrin complex (EMindL) Cu (N2) to air affords rapid,
quantitative uptake of O2 in either solution or the solid-state to yield (EMindL) Cu (O2). The …

The visible light-driven, catalytic aerobic oxidation of benzylic C–H bonds was mediated by
a MnIII corrolazine complex. To achieve catalytic turnovers, a strict selective requirement for …
