Coordination‐Driven Direct C─H Metalation of N‐Heterocycles With a Superbasic Co(II) Amide Co(TMP)2

open access: yesAngewandte Chemie, EarlyView.
By enabling regioselectivities that are inaccessible with conventional bases, this study introduces a Co(II) amide platform for the deprotonative C─H metalation of sensitive N‐heterocycles. Subsequent interception of the resulting Co(II) intermediates with external oxidants affords a family of sterically congested, TMP‐substituted heterocycles via C─N ...

Unlocking a Nitrosuccinate Lyase for Decarboxylative Enzymatic Hydronitration

open access: yesAngewandte Chemie, EarlyView.
The nitrosuccinate lyase CreD catalyzes C–NO2 bond formation using nitrite in water and shows synthetic practicality with high turnover numbers up to 102,000. A combination of protein engineering and computational methods helped to reveal the mechanistic principles that underpin this unique enzymatic activity.

Räumliche Entwicklung von Koks in ZSM‐5‐Katalysatoren während der Umwandlung von Methanol in Kohlenwasserstoffe, aufgezeigt durch in‐situ‐Röntgen‐Photoelektronenspektroskopie

open access: yesAngewandte Chemie, EarlyView.
Oberfläche enthüllt: Verkokung ist die zentrale Ursache für die Deaktivierung von Zeolithkatalysatoren. Mithilfe von In‐situ‐XPS in Verbindung mit ergänzenden Methoden identifizieren wir Unterschiede in der Bildungskinetik und Zusammensetzung von Oberflächenkoks auf industriell relevanten ZSM‐5‐Katalysatoren während der MTH‐Umwandlung und zeigen damit ...

Kooperative Redox‐Katalyse der N2O‐Zersetzung mittels auf Co3O4 geträgerten RhOx‐ und CeOx‐Spezies mit kurzreichweitiger Wechselwirkung

open access: yesAngewandte Chemie, EarlyView.
A short‐range Rh‐O‐Co‐O‐Ce interfacial moiety drives low‐temperature N2O decomposition via a cooperative redox cycle. Operando modulated‐excitation XAS with phase‐sensitive detection (ME‐XAS+PSD) tracks rapid, reversible Rh oxidation coupled to Co reduction. Combined kinetics and DFT rationalize the activity trends and identify the Rh‐O‐Co interface as

The Role of Zn–Hf Site Proximity and Oxygen Vacancies for Methanol Formation Over ZnHfOx Catalysts Under CO2 Hydrogenation Conditions

open access: yesAngewandte Chemie, EarlyView.
ZnHfOx catalysts enable highly selective hydrogenation of CO2 to methanol over a wide range of Zn contents, as the Zn‐VO‐Hf active motif (VO = oxygen vacancy) exists not only in solid solution‐type ZnHfOx for low Zn contents (≤ 35 mol%), but also as HfOx cluster/single atom decorated ZnO surfaces for Zn contents > 95 mol%.
