Copper Complexes with Arylated Triethylenetetramine Ligands: Reactivity Toward Dioxygen and Peroxides

European Journal of Inorganic Chemistry, EarlyView.
Here, we describe new Cu(I)/Cu(II) complexes based on arylated tren ligands and investigate their reactivity toward O2 and peroxides. Low‐temperature–stopped flow studies revealed the formation of transient copper–oxygen species, including superoxido, hydroperoxido, and alkylperoxido intermediates.

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

Chan–Lam Cross‐Coupling With Alkylboron Reagents: From Transmetallation to Radical Pathways

European Journal of Organic Chemistry, EarlyView.
Alkylative Chan–Lam coupling overcomes intrinsic transmetallation limitations of alkylboron reagents by engaging radical pathways. Recent advances reveal how radical and radical–polar crossover mechanisms enable mild C(sp3)—heteroatom bond formation. This minireview highlights key mechanistic insights and emerging strategies that transform alkylboron ...

Design, Synthesis, and Photophysical Studies of Functionalized Polyaromatic Isonitriles as Visible Light Photoredox Catalysts

European Journal of Organic Chemistry, EarlyView.
A new series of structurally rich polyaromatic isonitriles is presented as photoredox catalysts. Their photophysical properties are investigated by UV–Vis absorption and fluorescence measurements, combined with experimental and theoretical studies to evaluate both ground‐ and excited‐state redox properties.

Rh(III)‐Catalyzed [4+2] Annulation of Imidazoles With α‐Diazocarbonyl Compounds: Direct Access to π‐Conjugated Imidazole‐Fused Isoquinolinone

European Journal of Organic Chemistry, EarlyView.
A Rh(III)‐catalyzed [4 + 2] annulation of 2‐aryl imidazoles/benzimidazoles with α‐diazocarbonyl compounds is developed for the synthesis of π‐conjugated imidazo/benzimidazo[2,1‐a]isoquinolinones systems. Mechanistic studies and control experiment reveal that the reaction proceeds via imidazole‐directed ortho C(sp2)–H activation, followed by carbene C–H
