The Role of Iron‐Hyponitrite Intermediates in Biology and Insights From Synthetic Model Complexes

Chemistry – A European Journal, EarlyView.
Despite the difference in active site architecture, NO reduction by different NOR enzymes is expected to be linked by a common intermediate: hyponitrite (N2O22−). However, experimentally, very little is known about the coordination chemistry of iron with hyponitrite and the expected Fe‐hyponitrite intermediates.

Successive Azide and DNA Functionalization for Reversible and Controlled Association of Single‐Wall Carbon Nanotubes

Chemistry – A European Journal, EarlyView.
A newly synthesized bifunctional azide—diazonium linker allows robust one‐step introduction of azido groups to single‐wall carbon nanotubes. Versatility of the azido groups as reactive handles is demonstrated by further derivatization with 6‐carboxyfluorescein and oligonucleotides.

Catalyst‐Free Selective Reduction of Nitrogen Dioxide to Nitric Oxide

Chemistry – A European Journal, EarlyView.
Common main group reductants selectively convert nitrogen dioxide to nitric oxide in a catalyst‐free manner. Computational studies suggest divergent reaction pathways depending on the reductant employed. Where boranes and silanes proceed via a two‐electron process, and hydrogen surrogates undergo stepwise one‐electron processes.

Nitrooxylation in Organic Synthesis: From Classical Nitrate Ester Formation to Modern Catalytic Strategies

Chemistry – A European Journal, EarlyView.
Nitrooxylation—the installation of nitrate esters (–ONO2) has evolved from classical mixed‐acid protocols to catalytic and mechano‐, flow‐, photo‐, and electrochemical strategies. This review delineates ionic and radical manifolds for C–ONO2 bond formation, emphasizing mechanistic control, selected substrate scope, and selectivity.

Fluorogenic Sydnones for Bioorthogonal Labeling of DNA

Chemistry – A European Journal, EarlyView.
Conjugates of sydnones with cyanine‐styryl dyes combine bioorthogonal reactivity with fluorogenicity. The reactivity with bicyclo[6.1.0]non‐4‐yne (BCN)‐modified DNA showed second‐order rate constants of up to k2 = 2,300 M−1s−1 and fluorescence turn‐on by one magnitude of order.

A Unified Approach for the Synthesis of Conformationally Locked and sp2‐sp3 Fused Hybrids

Chemistry – A European Journal, EarlyView.
This study presents a systematic platform to build rigid sp2–sp3 hybrids via benzyne cycloadditions. Arene‑fused bicyclic oxa‐, aza‐, and carbocycles are converted into medicinally relevant amino acids and applied to Enalapril analogues synthesis. The hybrids combine aromatic interactions with 3D rigidity, tuning lipophilicity, pKa, and solubility ...

Cellular Membrane‐Targeted Europium(III) Probe for Selective and Time‐Resolved Detection of Peroxynitrite

Chemistry – A European Journal, EarlyView.
We report a cellular membrane‐targeted europium(III) probe, Eu.Chol, that enables selective, time‐resolved detection of peroxynitrite (ONOO−) at the cell membrane interface. Eu.Chol demonstrates efficient incorporation into liposomes and Jurkat cells, with minimal response to H2O2, establishing a modular platform for subcellular ONOO− sensing ...

Investigation of Electro‐Oxidation and Ozonation for Removal of Organics in Wastewater Derived From Recycling Process for Lithium‐Ion Batteries

CleanMat, EarlyView.
To develop recycling processes for lithium‐ion batteries, wastewater treatment for the removal of organic compounds originating from the electrolyte was investigated using electro‐oxidation and ozonation. Based on the results, this paper proposes a process which combines these two methods to remove alcohols derived from the solvent and additives ...
