Animal Models and Experimental Medicine, EarlyView.The antioxidant efficacy of Colocasia esculenta flower’s methanolic extract was assessed using 2,2′‐azino‐bis‐(3‐ethylbenzothiazoline‐6‐sulfonic) (ABTS) and 2,2‐diphenyl‐1‐picrylhydrazyl (DPPH) scavenging assay. The hepatoprotective effect was investigated by assessing liver injury indicators (amino transferase [ALT], aspartate amino transferase [AST],

Angewandte Chemie, EarlyView.A CuOx@NiBiOx core‐shell‐like catalyst is synthesized. Thanks to the Bi presence, the electronic structure of Ni is tuned, leading to better catalytic performance for glycerol oxidation compared to both CuOx and CuOx@NiOx catalysts. Additionally, coupling glycerol oxidation with CO2 reduction significantly reduces the operational voltage and the ...

Nitrate Reduction for Deaminative Suzuki–Miyaura Coupling of Anilines
Angewandte Chemie, EarlyView.We present a one‐step deaminative Suzuki–Miyaura‐type coupling of anilines via fleeting diazonium intermediate with nitrate and bisulfite as the reagents. This represents the first application of the nitrate reduction strategy in transition metal catalysis of diazonium chemistry.

Stochastic Hydrodynamic Velocity Field and the Representation of Langevin Equations
Annalen der Physik, EarlyView.A lumped method is proposed to account for both mean‐field hydrodynamics and stochastic fluctuations within the kinematic equations of motion, providing a regularized formulation of the overdamped approximation. The concept of stochastic realizability in broad sense is introduced based on the spectral properties of the Fredholm operator associated with

Site‐Selective Carbonylation of Azetidines via Copper‐Catalyzed Difluorocarbene Insertion
Angewandte Chemie, EarlyView.We disclose a site‐selective Cu‐catalyzed carbonylation of azetidines promoted by difluorocarbene insertion at low temperature, enabling access to a variety of functionalized γ‐lactams and a therapeutic agent for diabetes (40 examples). This skeletal expansion strategy provides a distinct disconnection approach to synthesize medicinally relevant five ...

A Bench‐Stable Fluorophosphine Nickel(0) Complex and Its Catalytic Application
Angewandte Chemie, EarlyView.We herein present the synthesis of a bench‐stable Ni(0) complex, [Ni(PFPh2)4], stabilized by vastly underexplored fluorophosphine ligands. The application of [Ni(PFPh2)4] in Suzuki–Miyaura and Kumada‐Tamao‐Corriu cross‐coupling reactions as well as in Buchwald–Hartwig C─N bond formation reactions, indicates its promising potential as alternative to ...
