Inverse Vulcanization Through Epoxide Chemistry: A Low Temperature Non‐Olefin Route to Sulfur‐Rich Polymer Networks

Angewandte Chemie, EarlyView.
Epoxide monomers undergo base‐catalyzed ring‐opening copolymerization with elemental sulfur to afford sulfur‐rich polymers under mild conditions. The resulting materials exhibit excellent mechanical performance, strong adhesion (up to 10 MPa on stainless steel), and outstanding reprocessability.

Unlocking a Nitrosuccinate Lyase for Decarboxylative Enzymatic Hydronitration

Angewandte 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.

Three Component Thio‐ and Carboboration of Alkynes: A Modular Route to Functionalised Bicyclic Boronates

Angewandte Chemie, EarlyView.
Three‐component thio‐ and carbo‐boration reactions to form functionalised benzoxaborinines and benzazaborinines are reported. The nucleophile scope includes thioethers, thiols, and (hetero)arenes. Mechanistic studies revealed a disparity between thioboration using thioethers and using thiols.

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

Angewandte 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 ...

A Mononuclear Ruthenium(V)‐Imido Complex With Hydrogen Bonding in the Second Coordination Sphere Forming Aziridines Without N‐Substituents From Alkenes in Water

Angewandte Chemie, EarlyView.
This study employs a RuV═NH complex with hydrogen‐bonding (HB) sites in the SCS to afford non‐N‐substituted aziridines selectively. Nitrogen‐atom transfer occurs from the RuV═NH complex to alkenes in water to produce aziridine derivatives in high yields.
