Interfacial Charge‐Transfer Enhancement via High‐Entropy Alloy Regulated MXene Heterostructures for Asymmetric Supercapacitor Applications

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A novel core‐shell HEA@MXene composite was synthesized to enhance supercapacitor electrochemistry. DFT simulations reveal the role of HEA doping in regulating the MXene interface. The HEA@MXene composite exhibits a high specific capacitance of 872 F g−1 at 1 A g−1 with remarkable stability in 1 M KOH.

Synthetic Strategies for the Construction of Cyclobutane‐Fused Heterocycles

European Journal of Organic Chemistry, EarlyView.
Cyclobutane‐fused heterocycles are important motifs commonly present in bioactive compounds, recognized for their rigid 3D structures that confer unique properties. However, synthesizing these compounds remains challenging. This review discusses current methods for their synthesis, such as photochemical, metal‐catalyzed, and Lewis acid‐mediated [2 + 2]

Selective N‐Functionalization of Pyrazoles

European Journal of Organic Chemistry, EarlyView.
This review traces the evolution of regioselective N‐functionalization strategies for pyrazoles, a key class of nitrogen heterocycles widely used in medicinal chemistry. Due to rapid tautomerism, N‐functionalization often lacks selectivity, leading to poor and unpredictable regioisomeric outcomes.

Gold(I)‐Catalyzed Annulation of Pyridines Containing Alkyne: Synthesis of N‐Alkenyl Pyridonyl Azides via Rearrangement

Journal of Heterocyclic Chemistry, EarlyView.
One‐pot gold(I)‐catalysts synthesis was developed in order to prepare N‐alkenyl 2‐pyridonyl azides. This method provides a series of N‐alkenyl 2‐pyridonyl azides in moderate to excellent yields (up to 94%). ABSTRACT A novel strategy, involving the preparation of gold‐catalyzed cyclization salts and the rearrangement of these salts in the presence of ...

All‐in‐One Interface Engineering From Bulk to Electrode Toward High‐Performance Micro‐Sized Silicon Anodes

Small, EarlyView.
Microsized silicon (µ‐Si, >1 µm) is one of the ideal anodes for lithium‐ion batteries. In this paper, an integrated co‐carbonization electrode (ICCE) without binder and conductive agent was prepared by precoating a uniform carbon layer on the surface of µ‐Si particles, which significantly improved the electrochemical performance.

Alkoxyallenes in Modern Synthesis: Reactivity, Catalysis, and Complexity Generation

Advanced Synthesis &Catalysis, Volume 368, Issue 17, 1 September 2026.
The last decade has witnessed a remarkable transformation in alkoxyallene chemistry. Although historically employed as synthetic equivalents of acrolein or as versatile 3C synthons, alkoxyallenes are now increasingly recognized as highly adaptable platforms for synthetic design.
