Radikale Kaskadenreaktion, welche die Kreuzkupplung von Olefinen mit der Smiles‐Truce‐Umlagerung kombiniert

Angewandte Chemie, EarlyView.
Wir stellen eine kobaltkatalysierte Radikalkaskade vor, die zwei Alken Ausgangsstoffe effizient miteinander verbindet und so in einem einzigen Schritt mehrere Bindungen aufbaut. Der Prozess beginnt mit einem kobaltkatalysierten Wasserstoffatomtransfer an eine Styrol‐Doppelbindung, gefolgt von einer Giese‐Addition.

Consequences of Medium‐Pore Zeolite Constraints for Alkene Cracking—The Case of n‐Pentene

Angewandte Chemie, EarlyView.
Alkene cracking in medium‐pore zeolites is governed by a balance of enthalpic and entropic effects. Intrinsic barriers are quantified and shown to be lower than for alkanes due to stabilization of carbenium‐ion‐like transition states. Confinement and extra‐framework aluminum modulate reactivity by tuning transition‐state energetics, providing a ...

From [NHC─H]• to Persistent σ‐Complex Radicals: Photoinduced Radical Chemistry of Imidazolium Salts

Angewandte Chemie, EarlyView.
Visible‐light excitation of electron donor–acceptor (EDA) complexes between imidazolium salts and triarylamines enables controlled single‐electron transfer (SET) and reveals a family of carbene‐centered σ‐complex radical cations. Cryogenic electron paramagnetic resonance (EPR) captures the elusive [NHC─H]• intermediate and its thermal evolution into ...
