Visible‐Light‐Initiated, Nickel‐Catalyzed Aminocarbonylation of Alkynyl Iodides to 2‐Ynamides
Visible light initiates a nickel‐catalyzed aminocarbonylation of alkynyl iodides, enabling the synthesis of 2‐ynamides under low carbon monoxide pressure. The method operates under mild conditions, tolerates a broad substrate scope, and proceeds through a light‐triggered nickel(I)/nickel(III) carbonylative pathway.

From classroom to clinic: Evaluating the educational utility of two Thiel embalming methods
Abstract Over three decades since its introduction, the Thiel embalming method remains a widely used and praised technique in anatomical education and clinical training. This study compared for the first time the Thiel original protocol (TO) and a Modified version (TM) across user groups—undergraduate medical students, student demonstrators in anatomy,

Pyrrolo[3,4‐b]pyridin‐5‐ones are assembled in one pot manner through an Ugi‐Zhu reaction coupled to a cascade sequence (aza Diels‐Alder/N‐acylation/decarboxylation/dehydration). Pyrrolo[3,4‐b]pyridin‐5‐ones are fluorescence probes for local viscosity, polarity, protic environments, and solid‐state emission.

This review describes cyclic voltammetry or chronamperometry of phenol derivatives, catecholamines, and hydroxylated naphthalenes on electrodes. Under strong oxidative conditions the solutes are mineralized, but in the electrochemical stability window of the solvent, the electrode undergoes passivation or deposition of porous (eventually conductive ...

Bench‐stable, low‐coordinated Pt‐germyl complexes enable regioselective 1,4‐hydrosilylation of α,β‐unsaturated enamides to form N,O‐silyl ketene acetals under mild conditions with broad functional‐group tolerance. These species undergo catalyst‐free CO2 carboxylation leading to α‐carboxylated amides in a fully atom‐economical tandem process.

Oxidative Generation and Reactivity of the Cyclopropyl Radical From a Martin Silicate
A photoredox strategy employing Martin silicates enables the oxidative generation and controlled capture of cyclopropyl radicals, including the naked one, long considered challenging intermediates. The method affords functionalized cyclopropanes through both Giese‐type additions and dual nickel/photoredox C(sp3)−C(sp2) cross‐couplings.

Integrin αVβ3‐targeting small‐molecule drug conjugates (SMDCs) were synthesized by conjugating a cryptophycin payload through a neutrophil elastase‐cleavable NPV‐PABC linker. RGD peptidomimetic and linker epimers served as controls for targeting and enzymatic cleavage, and the resulting conjugates displayed subnanomolar cytotoxicity in vitro.

Post‐Synthetic Functionalisation of Benzo[a]ullazines for Improving UV–Vis Absorption Profiles
Less accessible benzo[a]ullazines bearing several substituents have been successfully synthesised. Through their photophysical and electrochemical evaluation, the effects of substituting each carbon centre within this π‐system on their physical properties have been elucidated.

Surface‐functionalized gold nanoclusters (AuNCs) are synthesized in situ by chain‐end grafting of RAFT polyelectrolytes at room temperature directly in water. It leads to highly stable polymer‐AuNCs nanohybrids emitting near‐infrared photoluminescence with µs lifetimes. ABSTRACT With their photoluminescence properties, gold nanoclusters (AuNCs, d<2 nm)
