Thermal Nickel‐Catalyzed N‐Arylation of Sulfonimidamides With (Hetero)aryl Chlorides Enabled by PAd‐DalPhos Ligation

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
The nickel‐catalyzed S═NH N‐arylation of sulfonimidamides is described, with useful demonstrated substrate scope involving inexpensive and widely available (hetero)aryl chloride reaction partners, including the active pharmaceutical ingredient chlorpromazine.

Investigation of α‐Silylalcohols as Chiral Umpolung Carbanion Surrogates Through Stereospecific 1,2‐Brook Rearrangement

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Deprotonation of chiral α‐silyl secondary alcohols leads to masked polarity‐reversed chiral carbanions through stereospecific 1,2‐Brook rearrangement. In situ trapping with Weinreb amide electrophiles affords α‐hydroxyketones with moderate to excellent enantiospecificity (es).

Three-component Friedel-Crafts-type difunctionalization of ynamides with (hetero)arenes and iodine(iii) electrophile

open access: yes
The three-component Friedel-Crafts type functionalization of an electron-rich arene using an electrophile-activated alkyne can offer a strategy for rapidly constructing densely functionalized vinylarenes in a regio- and stereoselective fashion.

Bromonitroalkanes in Organic Synthesis

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
α,α‐Bromonitroalkanes (BNAs) exhibit chameleon‐like reactivity, serving as carbene, radical, carbanion, and carbocation synthons. This mini‐review summarizes the different reaction modes and highlights recent developments in thermal and photochemical processes. α,α‐Bromonitroalkanes (BNAs) exhibit chameleon‐like reactivity, serving as carbene, radical,

Flexible lithium‐ion batteries: Materials design, interfacial regulation, and strain‐adaptive device architectures

open access: yesFlexMat, EarlyView.
This review highlights recent advances in flexible lithium‐ion batteries for wearable and deformable electronics. It systematically examines deformable electrodes, mechanically compliant gel and solid‐state electrolytes, and strain‐adaptive cell architectures, alongside an analysis of mechano‐electrochemical coupling under dynamic deformation.

Air Pollution Quinones Impair Intestinal Barrier Integrity and Endoplasmic Reticulum in Differentiated Caco‐2 Cells

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Particulate matter (PM) is a major global health threat, linked to millions of deaths annually. Beyond inhalation, PM components reach the gastrointestinal tract through the mucociliary escalator or contaminated food and water. Among PM's organic fraction, redox‐active quinones such as 1,2‐naphthoquinone (NQ) and 9,10‐phenanthrenequinone (PQ ...
