Tailored Polymer‐Zeolite Imidazolate Framework Membranes for Aperture‐Matched C4 Hydrocarbon Separation

open access: yesAngewandte Chemie, EarlyView.
Mechanosynthesis of polyZIF overcomes MOF‐polymer phase incompatibility via in‐situ polymer‐Zn2+‐Im coordination networks. Pore architecture engineering yielded molecular‐sieving membrane transport channels that enhanced butadiene permeance to 332 GPU while maintaining outstanding selectivities against C4 hydrocarbons through the size‐exclusion ...

Imidazo[1,5‐a]pyridine – Eine Vielseitige Plattform für Strukturell Einzigartige N‐Heterocyclische Olefine und π‐Ausgedehnte Heterocyclen

open access: yesAngewandte Chemie, EarlyView.
Die Synthese von N‐heterocyclischen Olefinen (NHOs) auf der Basis eines Imidazo[1,5‐a]pyridin‐Gerüsts wird beschrieben. Während C5‐Alkyl‐ oder Aryl‐Substituenten stabile NHOs ergeben, induzieren Alkenyl‐ oder Alkinylgruppen an C5 eine 6‐endo‐Cyclisierung, um (Dihydro)imidazo[2,1,5‐de]chinolizine mit starken paratropen Ringströmen zu bilden.

Cooperative Photometallobiocatalysis: Nonheme Fe Enzyme‐Catalyzed Enantioconvergent Radical Decarboxylative Azidation, Thiocyanation, and Isocyanation of Redox‐Active Esters

open access: yesAngewandte Chemie, EarlyView.
Through the directed evolution of an underexploited nonheme Fe extradiol dioxygenase, we developed a unified cooperative photobiocatalytic strategy to allow for three types of enantioconvergent radical transformations, including azidation, thiocyanation, and isocyanation.
