Synthesis of a Novel Amine‐Based Curing Agent for Epoxy Resins Derived From Vanillin

Journal of Applied Polymer Science, Volume 143, Issue 39, October 15, 2026.
The four‐step synthesis of a new bio‐based amine hardener is described starting from vanillin as a bio‐based compound. The hardener ADBA was utilized to cure DGEBA and the resulting T g,tanδmax was determined via DMA. Compared to other bio‐based curing agents, our curing agent is obtainable in a high yield and leads to a superior T g of 135°C ...

Synthesis and Fluorescence Profiling of Naphthylamine Analogs

ChemBioChem, Volume 27, Issue 19, 14 October 2026.
N‐phenyl‐1‐naphthylamine (NPN) has been historically used as a probe to monitor gram‐negative bacterial outer membrane permeabilization, fluorescing only in hydrophobic environments. Herein, a 95‐membered naphthylamine library was synthesized to explore structure–fluorescence relationships, informed by density functional theory studies.

A Selectfluor‐based Polonovski Rearrangement Leading to Novel Entities for Synthetic and Medicinal Applications

Chemistry – A European Journal, Volume 32, Issue 38, 13 October 2026.
Starting from carboxylic acids and Selectfluor‐derivatives, functionalized diazabicyclooctanes can be obtained via a novel Polonovski‐type rearrangement proceeding under mild reaction conditions. Besides their use in organic synthesis the unique structure and reactivity of the rearrangement products enables applications in medicinal chemistry ...

Base and solvent dependency of an oxidative retro-alkylation of secondary and tertiary benzylamines

, 2013
An iodine and caesium carbonate amine oxidation protocol is described. Non-branched secondary benzylamines were cleanly oxidised to aldimines that could be isolated without the need for chromatography.

Palladium-Catalyzed Carbonylative Synthesis of Isoindolinones from Benzylamines with TFBen as the CO Source

, 2019
A palladium-catalyzed C–H carbonylation of benzylamines for the synthesis of isoindolinone scaffolds has been developed. This protocol is conducted under gas-free conditions by using benzene-1,3,5-triyl triformate (TFBen) as a convenient CO surrogate ...

Visible‐Light‐Initiated, Nickel‐Catalyzed Aminocarbonylation of Alkynyl Iodides to 2‐Ynamides

Advanced Synthesis &Catalysis, Volume 368, Issue 19, 1 October 2026.
Visible light initiates a nickel‐catalyzed aminocarbonylation of alkynyl iodides, enabling the synthesis of 2‐ynamides under low carbon monoxide pressure. The method operates under mild conditions, tolerates a broad substrate scope, and proceeds through a light‐triggered nickel(I)/nickel(III) carbonylative pathway.

Programming Structural Symmetry and Emission in Low‐Dimensional Hybrid Perovskites via Time and Temperature

Advanced Science, Volume 13, Issue 57, 14 October 2026.
We demonstrate programmable structural symmetry and emission in benzylammonium‐based low‐dimensional hybrid perovskites. Continuous shaking transforms orthorhombic platelets into a lower‐symmetry monoclinic phase with broadband emission, whereas thermal activation drives the reverse pathways toward a higher‐symmetry configuration resembling the ...
