Synthesis of Heterocyclic Scaffolds from Nitrobenzyl Alcohols Using Reduction‐Generated Azaquinone Methides and Cyclization

European Journal of Organic Chemistry, EarlyView.
Intramolecular cyclization to quench an in situ reduction‐generated azaquinone methide is a strategy that could be used for late‐stage heterocycle synthesis. Herein, synthetically accessible 4‐nitrobenzyl alcohols with a nucleophilic handle adjacent to the benzyl alcohol group are reduced under mild conditions to afford six‐ and seven‐membered ...

Silyl Rearrangements in Gold‐Catalyzed Transformations

European Journal of Organic Chemistry, EarlyView.
The synergy between the exceptional ability of gold catalysts to activate unsaturated substrates and the inherent tendency of organosilicon reagents to undergo silyl‐group rearrangements has unlocked a range of novel transformations, enabling access to otherwise challenging molecular architectures.

Recent Advances in Conjugated Microporous Polymers for Photocatalysis: Mechanism, Synthesis and Applications

Exploration, EarlyView.
Conjugated microporous polymers (CMPs) have attracted more and more attention as new photocatalysts due to their unique advantages such as high performance, long stability and strong light absorption. This review summarizes the application of CMPs as a photocatalyst in recent years and introduces the catalytic mechanism.

GC × GC‐TOF MS and Sensory Profiling of Aroma Compounds in Magnolia Species: Effects of Processing Methods on Volatile Retention in M. wufengensis

Flavour and Fragrance Journal, EarlyView.
The first comparative analysis of Magnolia scents reveals that M. wufengensis is characterised by a high aldehyde content, exhibiting a fresh, sweet, and fruity fragrance profile. Furthermore, freeze‐drying preserves 6.7 times more 2‐nonenal compared to shade‐drying, highlighting its superior efficacy in retaining key volatile compounds.

Heteroatom location‐ and orientation mode‐dependent reverse intersystem crossing rate in multiple resonance emitters

FlexMat, EarlyView.
By constructing two pairs of isomers with different heteroatom anchoring positions, the relationship between heteroatom location and orientation mode and reverse intersystem crossing rate constant (kRISC) in multiple resonance (MR) emitters is systematically investigated.

Conjugation‐mediated and polarity‐switchable interfacial layers for fast cycling of lithium‐metal batteries

InfoMat, EarlyView.
Thiophene‐embedded solid electrolyte interphase exhibits switchable polarity for uniform Li plating, and the electron‐rich cathode electrolyte interphase stabilizes high‐valence Ni ions in the cathode. These molecularly engineered interfacial layers enable fast cycling of lithium‐metal batteries for practical applications.
