1,1‐Disubstituted Vinylbromides: Versatile Building Blocks for the Synthesis of Nitrogen‐Containing Heterocycles

European Journal of Organic Chemistry, EarlyView.
1,1‐Disubstituted vinylbromides are key intermediates for constructing nitrogen‐containing heterocycles. This review provides an overview of the synthetic applications of 1,1‐disubstituted vinylbromides and summarizes recent developments in reaction methodologies, mechanistic insights, and the structural diversity of N‐heterocyclic compounds accessible

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

Fast Reduction of Nitroalkenes Into Nitroalkanes Under Continuous‐Flow Chemical Conditions

European Journal of Organic Chemistry, EarlyView.
Flow chemical synthesis was employed for the reduction of nitroalkenes to the corresponding nitroalkanes using sodium borohydride as the reducing agent. The reaction proceeds in only 150 s, affording products from good‐to‐excellent yields (61–96%). Herein, we describe an efficient and rapid continuous‐flow reduction of nitroalkenes to nitroalkanes. The

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 ...
