Shedding Light on Synthetic Autocatalysis: From Conventional Closed‐Shell Chemistries to Overlooked Open‐Shell Occurrences

Chemistry – A European Journal, EarlyView.
Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.

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.

Design, Synthesis, and Photophysical Studies of Functionalized Polyaromatic Isonitriles as Visible Light Photoredox Catalysts

European Journal of Organic Chemistry, EarlyView.
A new series of structurally rich polyaromatic isonitriles is presented as photoredox catalysts. Their photophysical properties are investigated by UV–Vis absorption and fluorescence measurements, combined with experimental and theoretical studies to evaluate both ground‐ and excited‐state redox properties.

Evaluation of Photophysical Properties and Biological Applications of Diarylmethanes

ChemistryOpen, Volume 15, Issue 6, June 2026.
The wide applications of diarylmethanes were investigated through various experimental and computational approaches. The solvent environment influences the electronic properties of diarylmethanes and hence their drug‐like properties. Interactions with PARP1 revealed stable binding supporting anticancer potential.

Selective Fluorescent Probe Based on Thiomethyl‐Substituted Bis(arylidene)ketone for Hypochlorite Detection in Water Samples

ChemistrySelect, Volume 11, Issue 21, 4 June 2026.
The synthesized probe (SMAK) is the first bis(arylidene)ketone derivative for hypochlorite sensing. It was prepared in one step following two alternative routes; the traditional solution method and a greener solvent‐free method. Probe was found to have excellent selectivity over interfering anions, cations and oxidants and the mechanism of sensing and ...
