Shedding Light on Synthetic Autocatalysis: From Conventional Closed‐Shell Chemistries to Overlooked Open‐Shell Occurrences

Chemistry – A European Journal, EarlyView.
Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.

Synthetic Strategies for Activity‐Based Probes to Decode Ubiquitin‐Like Modifiers

Chemistry – A European Journal, EarlyView.
ABSTRACT Ubiquitin‐like proteins (Ubls) such as SUMO, NEDD8, ISG15, URM1, UFM1, FAT10, ATG8/ATG12, and FUBI are essential regulators of cellular homeostasis, controlling processes from protein stability and trafficking to immune signaling and autophagy.

Nonlocal communication with photoinduced structures at the surface of a polymer film

, 2005
Nonlocal communication between two laser light beams is experimented in a photochromic polymer thin films. Information exchange between the beams is mediated by the self-induction of a surface relief pattern.

Generation of a Ground‐State Electron Donor Utilizing Stored Light Energy

Chemistry – A European Journal, EarlyView.
Chemically stored light energy enables the generation of dianion reductants (∼−2.7 V) from vicinal diols derived from diaryl ketone photodimerization. These ground‐state electron donors efficiently reduce challenging substrates at room temperature, including aryl bromides, alkyl iodides, and sulfonamides.

Bifunctional Photocatalysts: Exploiting Proximity for Enhanced Reaction Performance

Chemistry – A European Journal, EarlyView.
This review covers the application of the bifunctional approach to photocatalysis as a means to attain (enhanced) enantioselectivity, and, more in general, as a strategy to enhance the catalytic performance through an effective use of short‐lived reaction intermediates.

Expedient Discovery of a Metallaphotoredox Cyanomethylation for Synthesizing α‐Aryl Nitriles

Chemistry – A European Journal, EarlyView.
A metallaphotoredox cyanomethylation reaction has been developed for the synthesis of valuable α‐aryl nitrile intermediates. The methodology was successfully applied to diverse medicinally‐relevant substrates, providing an expedient route to anti‐cancer Senexin compounds, while also removing the need for toxic cyanide reagents. The mechanism was probed

Carbon‐Negative Upcycling of Sewage Sludge into Superiorly Stable Gel Via Liquid‐Phase Utilization Strategy for Water‐Remediation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work developed a low‐temperature sludge hydrothermal coupled with gel crosslinking strategy which could upgrade the waste liquid generated from sewage sludge hydrothermal treatment into the hydrothermal‐liquid‐gel. The inventive hydrothermal‐liquid‐gel exhibited the enhanced pollutant removal capability, high synthetic stability, and superior ...

Hypervalent Iodine‐Mediated Synthesis of Sulfones Using Organozinc Pivalates and Sulfinate Salts

European Journal of Organic Chemistry, EarlyView.
A general protocol for sulfone synthesis via sulfonyl‐containing hypervalent iodine reagents and organozinc pivalates is described. The method is practical, provides a broad scope of sulfone in moderate to high yield. bicyclo[1.1.1]pentane‐sulfones are also disclosed and a one‐pot synthesis of Diels–Alder adduct is presented. Sulfones are key motifs in

Chan–Lam Cross‐Coupling With Alkylboron Reagents: From Transmetallation to Radical Pathways

European Journal of Organic Chemistry, EarlyView.
Alkylative Chan–Lam coupling overcomes intrinsic transmetallation limitations of alkylboron reagents by engaging radical pathways. Recent advances reveal how radical and radical–polar crossover mechanisms enable mild C(sp3)—heteroatom bond formation. This minireview highlights key mechanistic insights and emerging strategies that transform alkylboron ...

A Sustainable Borrowing Hydrogen Strategy in Natural Deep Eutectic Solvents for the N‐Alkylation of Amines From Alcohols

European Journal of Organic Chemistry, EarlyView.
A sustainable, ligand‐free Pd‐catalyzed borrowing hydrogen protocol in a biodegradable hydrophobic natural deep eutectic solvent (NADES) (thymol/DL‐menthol) enables the N‐alkylation of primary amines with benzylic alcohols under mild, aerobic conditions, allowing efficient reuse of both catalyst and solvent for seven consecutive cycles. The hydrophobic
