Facile Access to N‐Substituted Pyridyl Ligands

Advanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
A modular, robust, and versatile Buchwald–Hartwig amination protocol that enables the rapid synthesis of bipyridine, phenanthroline, terpyridine, and pybox ligands bearing dialkylamine, diarylamine, and heteroaromatic N‐substituents. Pyridyl motifs equipped with N‐substituents can be powerful ligands for catalysis, yet their broader adoption is limited

Desymmetrization of Pseudo‐para Diformyl[2.2]Paracyclophane via Brønsted Acid‐Catalyzed Reductive Amination

Advanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
A highly stereoselective desymmetrization of pseudo‐para diformyl[2.2]paracyclophanes is developed via chiral Brønsted acid‐catalyzed reductive amination. This protocol provides efficient access to enantiopure planar chiral paracyclophanes with broad substrate scope, excellent enantioselectivity, and versatile postsynthetic functionalization. Access to

Highly Lewis Acidic In Situ‐Generated Boronic Acid Ester: A Practical Catalyst for Hosomi–Sakurai Conjugate Addition, Carbonyl‐Ene Reaction, and Silane‐Mediated Amide Reduction

Advanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
An exceptionally Lewis acidic boronic acid ester, generated in situ from pentafluorophenylboronic acid and tetrabromonaphthalenediol, catalyzes three important chemical transformations at 1–10 mol% loading: the Hosomi–Sakurai allylation of α,β‐unsaturated ketones, intermolecular carbonyl‐ene reactions, and the reductions of tertiary amides to amines ...

Investigating the Reactivity and Selectivity in Nucleophilic Fluorination of Secondary Alkyl Bromides and Mesylates: Assessment of the Effect of Counterion and Bulky Alcohols

European Journal of Organic Chemistry, Volume 29, Issue 17, 5 May 2026.
Hydrogen bonding provided by pinacol or 2‐trifluoromethyl‐2‐propanol enhances the selectivity of nucleophilic fluorination of several secondary alkyl bromides or mesylates. Synthesis of secondary alkyl fluorides via nucleophilic substitution faces the problem of high competition with E2 processes. This competition depends on the chemical environment of

Carbon Dot Self‐Assembly: Bottom‐Up Fabrication, Morphological Evolution, Luminescence Regulation, and Advanced Applications

Aggregate, Volume 7, Issue 5, May 2026.
The self‐assembly of carbon dots, which enables precise control over their macroscopic architectures and collective properties, profoundly enhances their functionality. This review systematically summarizes the field through four key aspects—morphology control, luminescence modulation, assembly mechanisms, and advanced applications—and thereby offers a

Carbon Dots With Aggregation‐Dependent Photoluminescence and Application in Rewritable Water‐Jet Printing

Aggregate, Volume 7, Issue 5, May 2026.
Carbon dots demonstrate aggregation‐dependent photoluminescence. Through concentration control, their emission color can be continuously tuned from green to red. In a different approach, solvent‐induced self‐assembly yields size‐tunable spherical structures with distinct AIE features.

Spectroscopy and Conformer‐Selective Photoelectron Circular Dichroism of Chiral Molecules

Chemistry – An Asian Journal, Volume 21, Issue 9, 14 May 2026.
Photoelectron circular dichroism (PECD) is a forward–backward asymmetry in the angular distribution of the electrons emitted by a chiral molecule ionized by a circularly polarized light (CPL). Its sensitivity to conformation is studied by one‐photon or resonance‐enhanced two‐photon ionization, the latter being conformer‐selective.

Polyoxometalates for Health, Electronics, Energy, and the Environment: Challenges, Opportunities, and Future Horizons

ChemistryEurope, Volume 4, Issue 5, May 2026.
Polyoxometalates (POMs), illustrated as lemon‐like cars racing along a winding road, symbolize the accelerating progress of POM research toward technological applications. Global research communities, recent advances, and emerging opportunities highlight how coordinated efforts drive the transition of POM science from molecular discovery to deployable ...
