Mechanistic and Reactivity Insights into Diboron‐Mediated NN and NN Bond Scission

European Journal of Organic Chemistry, EarlyView.
This review highlights the emerging ability of diboron reagents to cleave both π‐bonded (N=N) and σ‐bonded (N—N) nitrogen–nitrogen linkages, integrating mechanistic understanding with recent synthetic applications. Diboron reagents have emerged as versatile reducing agents capable of transforming a broad range of functional groups through pathways like

Iminodirhodium‐ and Iminocopper‐Catalyzed CH Activation: Chemoselective Oxidation of Alcohols and Aldehydes via Intermolecular Hydride Abstraction

European Journal of Organic Chemistry, EarlyView.
Chemoselective hydride abstractor iminometalloids, derived from O‐mesylacetoxime (MAO) using Rh2(II/II) or Cu(I) catalysts, can activate the C–Hα bonds of alcohols and aldehydes ultimately forming ketones, carboxylic acids, and esters even in the presence of C–H bonds with comparable bond strengths.

Mesityl‐Substituted Azuleno[1′,2′:4,5]pyrrolo[2,3‐b]quinoxalines: Synthesis, Functionalization, Photophysical, and Electrochemical Properties

European Journal of Organic Chemistry, EarlyView.
Azuleno[1′,2′:4,5]pyrrolo[2,3‐b]quinoxaline with a mesityl group as a solubilizing group was synthesized. By synthesizing derivatives in which various functional groups were introduced into two electronically distinct sites, the pyrrole nitrogen atom and the azulene five‐membered ring, we were able to reveal that the photophysical and electrochemical ...

Electrochemical Three‐Component Synthesis of Heteroaryl Sulfonates

European Journal of Organic Chemistry, EarlyView.
An electrochemical, metal‐free three‐component strategy for direct C(sp2)─H sulfonation of electron‐rich heteroarenes using SO2 and alcohols is described. Utilizing inexpensive graphite electrodes and practical SO2 stock solutions under mild conditions, this method provides straightforward access to heteroaryl sulfonates from simple building blocks ...

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, EarlyView.
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.
