Electro-Oxidation of Glycerol on Core–Shell M@Pt/C (M = Co, Ni, Sn) Catalysts in Alkaline Medium

Energies
This study explores the development of core–shell electrocatalysts for efficient glycerol oxidation in alkaline media. Carbon-supported M@Pt/C (M = Co, Ni, Sn) catalysts with a 1:1 atomic ratio of metal (M) to platinum (Pt) were synthesized using a ...

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 ...

Highly Stable and Minimally Pt‐Loaded Multiporous Bimetallic Matryoshka Heterostructures for Efficient Hydrogen Evolution Reaction via pH‐Dependent Mechanistic Decoupling

Advanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
Highly uniform, multi‐porous Au–Pt Matryoshka heterostructures were synthesized via a facile galvanic replacement reaction using Au@Ag coreshells as sacrificial templates. By precisely tuning the Au/Pt composition, the catalysts were optimized for the hydrogen evolution reaction (HER), exhibiting outstanding efficiency and ultra‐high stability in both ...

Synthesis of a π‐Extended Phenazine Diimide Derivative and Characterization of Its Closed‐Shell Reduced States

Chemistry – A European Journal, Volume 32, Issue 17, 5 May 2026.
In this work, the synthesis and characterization of novel π‐extended phenazine diimides is reported. The derivatives undergo differential reduction to a dihydrophenazine or Meisenheimer form depending on the reaction conditions employed. The outcome of this work highlights the paramount importance of structural design in determining the nature of the ...

Boosting Photo‐Pyroelectric Effect via Tunable Polarization and Interfacial Defect Engineering

Advanced Science, Volume 13, Issue 25, 4 May 2026.
This study reports Ba(Ti0.85Zr0.15)O3 nanocatalysts with enhanced polarization and oxygen‐vacancy‐rich interfaces for efficient NIR‐II photo‐pyroelectric therapy. Zr doping boosts the pyroelectric coefficient and accelerates polarization switching, while oxygen vacancies improve photothermal conversion and surface reactivity.

Dual‐Phosphorus, Dual‐Nitrogen‐Embedded Corannulene: Synthesis, Structure, and Electronic Coupling

ChemistryEurope, Volume 4, Issue 5, May 2026.
P2N2‐TBC, a corannulene‐based bowl structure incorporating two phosphorus and two nitrogen atoms, represents the first P2N2‐embedded heterobuckybowl. The cis and trans stereoisomers of this compound display distinct packing motifs, leading to markedly different electronic coupling patterns.
