Chemical Properties of an Aryloxenium Cation with a Triplet Electronic Ground State

open access: yesChemistry – A European Journal, Accepted Article.
Aryloxenium cations contain a formally positively‐charged, monovalent oxygen atom with an incomplete electron shell. In spite of this unusual structural element, they are key intermediates in many important processes, such as biological oxidation reactions and the industrial generation of thermoplastics.

Dihalogens Binding and Activation by Imidazoline‐2‐Chalcogenone Model Derivatives: Insight from a Computational Approach

open access: yesChemistry – A European Journal, EarlyView.
1,3‐dimethyl‐4‐imidazoline‐2‐chalcogenones react with dihalogens, initially forming a charge‐transfer (CT) adduct, which may evolve to the most stable T‐shaped hypercoordinate (TY) species. However, in silico results show that the CT adduct is more stable than the corresponding TY species for the sulfur and iodine combination.

Synthesis and 64Cu‐Radiolabeling Strategies of Small Organic Radioconjugates Based on the AMD070 Scaffold

open access: yesChemMedChem, Accepted Article.
CXCR4 is a transmembrane receptor overexpressed in a large variety of cancer cells. In addition to classical antibody‐ and peptide‐targeting for the development of Positron Emission Tomography (PET) radiopharmaceuticals, this receptor possesses a range of small organic inhibitors that can be exploited. These are based mainly on nitrogen‐rich scaffolds,
