Impact of Electronic Substitution and Planarization on the Photophysical Properties of 2‐(2′‐Hydroxyphenyl)benzoxazole or 2‐(2′‐Hydroxyphenyl)‐Dimethylindole

European Journal of Organic Chemistry, Volume 29, Issue 28, 25 July 2026.
We report the synthesis, structural characterization, and photophysical investigation of a series of Excited‐State Intramolecular Proton Transfer‐active HBO and HDMI derivatives. By varying heterocyclic cores, substituents, and ethynyl planarization, we establish structure–property relationships governing fluorescence behavior.

A Ruthenium‐(Ph‐BPE) Catalyst for Asymmetric Alkynylation of Fluoral: Enantioselection From 1 of 12 Fluxional Stereogenic‐at‐Ruthenium Complexes

Angewandte Chemie International Edition, Volume 65, Issue 30, 20 July 2026.
The first enantioselective alkynylations of aqueous fluoral are described. These processes are catalyzed by an iodide‐bound ruthenium‐(Ph‐BPE)‐catalyst; an octahedral metal complex that can exist as 12 diastereomeric‐at‐metal isomers. Calculations reveal that 2 of 12 stereoisomeric complexes account for 99.9% of the Boltzmann population and that ...

Importance of Interfacial and Intraparticle Conductivity Enhancement in the Electrochemical Response of Composite Electrode Materials in 3D‐Printed Supercapacitors

ChemElectroChem, Volume 13, Issue 14, 17 July 2026.
Electrochemical performance in 3D‐printed supercapacitors containing pseudocapacitive materials and carbon conductive additives is governed by both intraparticle conductivity within the composite electrode and interfacial conductivity at the printed current collector.

Safracin B as a Synthetic Linchpin: From Natural Product to Drug Intermediate and Beyond

European Journal of Organic Chemistry, Volume 29, Issue 27, 17 July 2026.
Safracin B is employed as a key precursor for the streamlined preparation of cyanosafracin B and safracin A. Careful tuning of the reaction parameters affords these derivatives in high efficiency, and full nuclear magnetic resonance signal assignments are established for the complex safracin frameworks.

Mechanochemistry Meets Catalysis: Metal Complexes for Greener Organic Transformations

Angewandte Chemie, Volume 138, Issue 29, 13 July 2026.
Mechanochemistry is redefining metal catalysis by controlling catalyst formulation, speciation, and deployment. This Review shows how milling, LAG, RAM, and TSE enable rapid metal‐complex assembly, distinctive catalytic manifolds, and scalable synthesis beyond solution chemistry.

Synthesis and Properties of Cross‐Shaped Donor–Acceptor Dyes: Tunable Emission From Visible to Near‐Infrared in Solution and Solid‐State

European Journal of Organic Chemistry, Volume 29, Issue 27, 17 July 2026.
A comprehensive investigation (synthesis, electrochemistry, photophysics, and theory) of seven new cross‐shaped dyes based on N,N,N’,N’‐tetraphenyl‐1,4‐phenylenediamine cores substituted with different electron‐withdrawing groups, reveals tunable emission properties spanning the visible to near‐infrared range, both in solution and in the solid state ...
