Geminale Difunktionalisierung von Ketonen durch C–S Bindungs‐insertion photogenerierter Donor–Donor Diazoverbindungen

open access: yesAngewandte Chemie, Volume 138, Issue 25, 15 June 2026.
Die geminale Difunktionalisierung leicht verfügbarer Bausteine ermöglicht einen schnellen Zugang zu molekularer Komplexität. Diese Arbeit stellt eine Strategie vor, um zwei unterschiedliche funktionelle Gruppen an einem Carbonylkohlenstoff zu installieren, indem dieser in eine Donor–Donor‐Diazo‐Verbindung überführt wird. Die Methode ist sowohl im Batch‐

Molecular–Polymeric Hybrid Photocathodes for CO2 Reduction: A Modular Approach to Sustainable Photoelectrocatalysis

open access: yesChemElectroChem, Volume 13, Issue 10, 19 May 2026.
CP/PPy/Re–Ru is a hybrid molecular–polymeric photocathode prepared in a simple two‐step process by depositing catalytically active complexes onto a polypyrrole backbone on carbon paper. Under photoelectrocatalytic conditions, it achieves 60%–70% Faradaic efficiency for CO. Even in membrane‐free operation, continuous CO evolution is maintained for up to

Ligand Co‐Deposition in Focused Electron Beam Induced Nanoprinting: A Predictive Composition Model

open access: yesSmall Methods, Volume 10, Issue 3, 9 February 2026.
Nanoprinting using focused electron beam induced deposition (FEBID) with metalorganic molecules (ML) offers unparalleled spatial resolution and flexibility in 3D shape design. Here the key feature of nanoprint material is addressed ‐ its metal composition.

Online Coupling High‐Temperature Electrolysis with Carbonylation Reactions: A Powerful Method for Continuous Carbon Dioxide Utilization

open access: yesAngewandte Chemie, Volume 137, Issue 22, May 26, 2025.
A continuous process for carbonylation reactions based on the online coupling of dry, high‐temperature CO2 electrolysis with a coil reactor has been reported. The strategy relies on producing CO/CO2 mixtures onsite, without H2 or H2O entering the product gas, thus providing a safe and fast concept for the synthesis of several carbonyl compounds.
