Constructing Enzyme‐Inspired Multisite Synergistic Catalyst for Promoting CO2 Electroreduction to Ethylene at pH Universal Condition

Carbon Energy, EarlyView.
A rational synthesis strategy was developed to construct enzyme‐inspired Cu‐AM catalysts with well‐defined multisite architectures. This catalytic system enables highly selective electrochemical CO2 reduction to C2H4 under pH‐universal conditions, delivering exceptional Faradaic efficiencies across acidic, neutral, and alkaline electrolytes.

A Mononuclear Scenario for the Copper‐Catalyzed Monooxygenation of Phenolic Substrates

Chemistry – A European Journal, EarlyView.
ABSTRACT Whereas a dinuclear pathway applies to the monooxygenation of phenols by the type 3 copper enzyme tyrosinase, a mononuclear pathway has been identified for the same reaction in corresponding small‐molecule systems. DFT calculations of five copper model complexes reveal that the latter mechanism is energetically feasible, identifying all ...

Simple Guanosine—Amino Acid Hybrids as Low Molecular Weight Hydrogelators

Chemistry – A European Journal, EarlyView.
Unexplored guanosine‐amino acid derivatives act as low molecular weight hydrogelators. Gelation is triggered by K+ ions and pH changes and relies on G‐quadruplex formation. Small changes in the amino acid structure have a strong impact on the mechanical properties of the gels.

When Light Challenges Heat: Mechanistic Insights Into a Reaction Competing With Cadogan Cyclisation in Nitro‐Perylenediimides

Chemistry – A European Journal, EarlyView.
Visible‐light irradiation of nitro‐perylenediimide in the presence of triphenylphosphine reveals an unexpected pathway competing with the classical Cadogan cyclization. Mechanistic investigations uncover the rapid and selective formation of bay‐functionalized 1‐iminophosphorane‐12‐hydroxy perylenediimide derivatives.

Monosubstituted N‐Arylhydroxylamine Chemistry: Integrating Contemporary Synthetic Approaches for the Efficient Construction of Diverse Heterocyclic Scaffolds

Chemistry – A European Journal, EarlyView.
Monosubstituted N‐arylhydroxylamines represent a unique subclass of hydroxylamines that act as pivotal intermediates in redox transformations and as versatile platforms for further synthetic transformations. They serve as key building blocks in the synthesis of architecturally complex heterocycles and other valuable organic compounds.

State‐of‐the‐Art and Synthetic Challenges for Hydrosilane Production

Chemistry – A European Journal, EarlyView.
The synthesis of hydrosilanes is currently energy intensive and their recycling is not considered. However, these compounds are important in many industrial fields but also for the valorization of oxygenated waste, towards a circular economy. This review compares the available synthetic routes and highlights the remaining challenges for the production ...
