A High Energy Barrier DyIII2 Single‐Molecule Magnet Supported by a Bulky, Anionic N–O Bridging Ligand

Chemistry – A European Journal, EarlyView.
Complex [Dy2(hynad)2(dbm)4] was prepared by the employment of the anionic N–O‐based bridging and chelating N‐hydroxy‐1,8‐naphthalimide ligand, featuring a {Dy2(µ‐OR)2}4+ core and exhibiting zero‐field SMM behavior with a Ueff value of 171 K and double‐S‐shaped hysteresis loops, open up to 3.5 K.

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.

Synthesis and Functional Properties of Fluorinated Phosphonate‐Substituted Porphyrins: Excellent Photosensitizers and Robust Precursors for Photoactive Langmuir–Schaefer Films

Chemistry – A European Journal, EarlyView.
This is a comprehensive study of new family of high functionalized meso‐tetraarylporphyrins. A synthetic approach to phosphonate‐substituted fluorinated porphyrins was developed. These compounds were investigated with respect to singlet oxygen generation and photostability.

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.

Covalent Insertion of a Mn(Salen) Type Complex in Cross‐Linked Protein Crystals: Design of an Enantioselective Artificial Epoxidase

Chemistry – A European Journal, EarlyView.
An Artificial metalloenzyme was designed by a Michael addition between a MnSalen complex and a cysteine residue within NikA crystals. The heterogeneous catalyst was found capable of an enantioselective and stereospecific epoxidation of cis‐β‐methylstyrene in cristallo.

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.
