Isolation and Structural Characterization of Se‐Hügerschoff Intermediates Derived From 4‐Bromoaniline

Journal of Heterocyclic Chemistry, EarlyView.
Isolation and characterization of Se‐brominated Hügerschoff intermediates enable structural and mechanistic insight into seleno‐Hügerschoff cyclization to 2‐aminobenzoselenazoles. ABSTRACT A brominated intermediate within the Hügerschoff reaction has long been postulated but never directly observed.

3-Hydroxy-2-phenyl-2,3,3a,7a-tetrahydro-1H,5H-pyrano[3,2-b]pyrrol-5-one: crystal structure and Hirshfeld surface analysis

Acta Crystallographica Section E: Crystallographic Communications, 2017
The title isoaltholactone derivative, C13H13NO3, has an NH group in place of the ether-O atom in the five-membered ring of the natural product. The five-membered ring is twisted about the N—C bond linking it to the six-membered ring, which has a half ...

Organic Clusters With Well‐Defined Structure via Scaffold Confinement

Transformative Chemistry, EarlyView.
Using 3D‐shaped cyclic hydrocarbon scaffolds to spatially isolate electron‐rich moieties yields organic clusters with well‐defined structure, which will inspire further investigations into the in‐depth understanding of the underlying luminescence mechanism and facilitate quantitative and theoretical description of nonconventional luminophores ...

Spin Crossover around Room Temperature: Effects of Remote Ligand Symmetry Breaking within Jäger‐Type Iron(II) Complexes

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
Remote symmetry breaking in Jäger‐type iron(II) complexes shifts stepwise spin crossover (SCO) profiles to continuous profiles with transition temperatures around room temperature. In a bottom‐up approach, we studied the feedback of slight molecular modifications on the spin crossover (SCO) properties of otherwise structurally conserved iron(II ...

Bis[N-2-hydroxyethyl,N-methyldithiocarbamato-κ2S,S)'-4-{[(pyridin-4-ylmethylidene)hydrazinylidene}methyl]pyridine-κN1)zinc(II): crystal structure and Hirshfeld surface analysis

Acta Crystallographica Section E: Crystallographic Communications, 2017
In the title compound, [Zn(C4H8NOS2)2(C12H10N4)], the ZnII atom exists within a NS4 donor set defined by two chelating dithiocarbamate ligands and a pyridyl-N atom derived from a terminally bound 4-pyridinealdazine ligand.

Phase‐Engineered CuS on rGO Nanoflowers Directs Selectivity From Formate to Ethanol

ChemElectroChem, Volume 13, Issue 9, 5 May 2026.
Copper sulfide nanoflowers grown on reduced graphene oxide undergo a phase transition to metastable digenite (Cu7.2S4), enabling efficient CO2 electroreduction. The optimized catalyst achieves 82% Faradaic efficiency for formate, while tuning rGO content shifts selectivity toward ethanol.
