Mechanistic Promiscuity in Cobalt Mediated CO2 Reduction Reaction: One‐ versus Two‐Electron Reduction Process

Angewandte Chemie International Edition, Accepted Article.
We compare the carbon dioxide reduction (CO2RR) activity and selectivity of the complexes [(Hbbpya)CoII]2+ and [(Mebbpya)CoII]2+, which contain two 2,2′‐bipyridine chelating groups linked by ‐NH or ‐NCH3 moieties, respectively. Whereas [(Hbbpya)CoII]2+ forms CO under electrocatalytic conditions in presence of phenol (PhOH) with high selectivity ...

Photo‐controlled Release of Urea Enables the Detection of Urea‐Urease Intermediates by cryo‐FTIR

Angewandte Chemie International Edition, Accepted Article.
Caged compounds are a valuable tool to photocontrol the release of enzymatic substrates in a reaction. For example, caged urea molecules were proposed to control urea delivery to urease reactions and aid the determination of the catalytic mechanism of this enzyme.

Influence of Ligand Design and Non‐Covalent Interactions on the Isoselective Ring‐Opening Polymerization of rac‐β‐Butyrolactone Using Salan and Salalen Rare‐Earth Metal Catalysts

Angewandte Chemie International Edition, EarlyView.
Polyhydroxybutyrates are key sustainable polyesters, but controlling the stereoregularity is crucial for exhibiting the most promising thermal and mechanical properties. Highly active rare‐earth metal salan/salalen complexes yield isotactic (Pm up to 0.96 at 0 °C) or syndioenriched (Pr up to 0.91) PHB, depending on the steric demand of the ligand and ...

Ruthenium Catalyzed Ortho‐Arylation Reaction of Benzoic Acids with Arylthianthrenium Salts

Angewandte Chemie International Edition, EarlyView.
A catalytic ortho‐arylation method has been developed to convert arylthianthrenium salts into carboxylate‐functionalized biaryls, which can be removed in situ or used for further derivatization. This reaction is broadly applicable to (hetero)arenecarboxylic acids, with excellent functional group compatibility and orthogonality to cross‐couplings ...

Machine learning‐augmented molecular dynamics simulations (MD) reveal insights into the disconnect between affinity and activation of ZTP riboswitch ligands

Angewandte Chemie International Edition, Accepted Article.
The challenge of targeting RNA with small molecules necessitates a better understanding of RNA‐ligand interaction mechanisms. However, the dynamic nature of nucleic acids, their ligand‐induced stabilization, and how conformational changes influence gene expression pose significant difficulties for experimental investigation.
