Intramolecular N···F Pnictogen Bond Mitigates the Explosive Behavior of Azido‐L‐Phenylalanines

open access: yesChemistryEurope, EarlyView.
An intramolecular N···F pnictogen bond is the key for the chemical stabilization of the fluorinated azido‐L‐phenylalanines, mitigating the risk of explosion and thus facilitating the handling and storage of these materials. Organic azides are versatile intermediates but are plagued by intrinsic instability and potential explosiveness. Here, it is shown

Dimethylsulfoxide (DMSO) clusters dataset: DFT relative energies, non-covalent interactions, and cartesian coordinates

open access: yesData in Brief, 2022
Theoretical understanding of dimethylsulfoxide (DMSO) liquid depends on the understanding of the DMSO clusters. In this work, we provide the structures and the energetics of the DMSO clusters.

Unlocking Heterobimetallic Architectures in a Symmetric PNNP Ligand Environment

open access: yesChemistry – A European Journal, EarlyView.
A symmetric PNNP ligand enables the modular assembly of heterobimetallic ZnRu and CoRu complexes from a mononuclear Ru(II) precursor. Ligand deprotonation triggers dearomatization and contraction of the metal–metal distance. Combined DFT and QTAIM analyses reveal metallophilic interaction in CoRu but not in ZnRu, highlighting controllable geometric and

A Crystalline Mono‐Coordinate Indium(I)‐Phosphaalkenyl

open access: yesAngewandte Chemie, Volume 138, Issue 8, 16 February 2026.
The redox neutral carbometallation of a phospha‐alkyne using the dimeric indium(I) compound (InTer)2 is reported. This reaction affords a mono‐coordinate indium(I) compound that can reversibly extrude the phospha‐alkyne upon addition of a Lewis acid. Abstract The synthesis of the mono‐coordinate indium(I) compound In[C(Ad)═PTer] (Ad = 1‐adamantyl, Ter =

Charge State Influence on Stability and Isomerism in Dehydrogenated PAHs: Insights from Anthracene, Acridine, and Phenazine

open access: yesChemPhysChem, Volume 26, Issue 6, March 15, 2025.
The ionization of anthracene, acridine, and phenazine has been explored, along with the removal of one and two hydrogen atoms, to provide valuable information for astrochemists and to understand the behavior of the resulting structures and their electronic reorganization. Abstract In this study, we systematically explored the stability and isomerism of

Effect of Substitution of Hydrogen Atoms in the Molecules of Anthrone and Anthraquinone

open access: yesMolecules, 2021
The geometry of anthrone and anthraquinone—natural substances of plant origin—was investigated under the substitution of hydrogen atoms in side aromatic ring and, for anthrone, also in the central ring. A significant influence of substitution on geometry

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

open access: yesJournal 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.
