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

Angewandte Chemie, EarlyView.
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‐

Aldehyde–Olefin Couplings by Photoinduced Reduction of Electron‐Deficient Olefins with Hantzsch Ester Anions

Angewandte Chemie, EarlyView.
Single‐electron transfer‐mediated reductive carbonyl–olefin couplings are valuable carbon–carbon bond forming reactions. However, limitations persist for couplings of aliphatic aldehydes with electron‐deficient olefins. Here, we report a simple, photocatalyst‐free protocol that overcomes these limitations by using a Hantzsch ester anion as a ...

Circularly Polarized Luminescent and Melt‐Processable Copper(I)‐Organic Glasses Based on 2,2′‐Bis(diphenylphosphino)‐1,1′‐binaphthyl

Angewandte Chemie, EarlyView.
Homochiral Cu(I) cyanide complexes based on 2,2’‐bis(diphenylphosphino)‐1,1’‐binaphthyl (BINAP) form melt‐quenched and desolvation‐derived metal–organic glasses that exhibit circularly polarized thermally activated delayed fluorescence (TADF) at room temperature, enabling processable chiroptical materials.

Aziridinierung eines einzelnen Kohlenstoffatoms in Alkenen mittels Energietransferkatalyse

Angewandte Chemie, EarlyView.
Im Gegensatz zur traditionellen Alken‐Aziridinierung über (formalen) Nitren‐Transfer berichten wir hier über eine Strategie zur intermolekularen Aziridinierung eines einzelnen Alken‐Kohlenstoffatoms bei zusätzlicher Funktionalisierung der anderen Position. Durch Energietransfer‐ (EnT‐)Katalyse werden Alkenylboronate und ‐silane in reaktive Intermediate
