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 …

Copper is one of the most abundant and less toxic transition metals. Nature takes advantage
of the bioavailability and rich redox chemistry of Cu to carry out oxygenase and oxidase …

Electrocatalytic approaches to the activation of unsaturated substrates via reductive
concerted proton-electron transfer (CPET) must overcome competing, often kinetically …

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 …

A new Kinugasa reaction protocol has been elaborated for the one-pot synthesis of 4-
substituted β-lactams utilizing calcium carbide and nitrone derivatives. Calcium carbide is …

Tyrosinase (EC 1.14. 18.1), a copper-containing monooxygenase, catalyzes the conversion
of phenol to the corresponding ortho-quinone. The Streptomyces tyrosinase is generated as …

Melanoma is a type of highly malignant and metastatic skin cancer, and early detection of
melanoma by analyzing the level of its biomarker may decrease the likelihood of mortality. In …

We describe the use of simple copper‐salt catalysts in the selective aerobic oxidation of
amines to nitriles or imines. These catalysts are marked by their exceptional efficiency …

High-valent metal species are often invoked as intermediates during enzymatic and
synthetic catalytic cycles. Anionic donors are often required to stabilize such high-valent …
