Elementspuren in der elektrochemischen reduktiven Aminierung von Aceton: Enthüllung von Bi als Ersatz für Pb

Angewandte Chemie, EarlyView.
Diese Studie untersucht den Einfluss von Spuren diverser Elemente des p‐Blocks in der elektrochemischen reduktiven Aminierung, wobei sich für Pb mit Bi eine weniger toxische Alternative gezeigt hat. Die Verwendung von Bi als Additiv wurde weiter optimiert, indem der Einfluss der Additivkonzentration, der Reaktionstemperatur und des Kathodenmaterials ...

Regiodivergent C3 and C4 Amination of Quinolines via Radical and Ionic Pathways

Angewandte Chemie, EarlyView.
A regiodivergent strategy converts a single N‐aminoquinolinium precursor into either C3‐ or C4‐aminated quinolines. Nucleophile‐induced dearomatization diverges into light‐driven N‐centered radical capture (C3) or base‐promoted SNAr (C4), enabling rapid assembly of aminoquinoline libraries and late‐stage diversification.

Bridged Pyrroloindole‐CAYC‐Gold Complexes: Harnessing Weak Secondary Intramolecular Au···H−C(sp3) Interactions in Gold(I) Catalysis

Angewandte Chemie, EarlyView.
We present a new class of electronically and sterically hindered N‐heterocyclic carbenes, referred to as bridged cyclic (amino)ylide carbene (bCAYC), where 9H‐pyrrolo[1,2‐a]indole acted as carbene core and diaryl sulfonium as ylide partner. Corresponding bCAYC‐Au(I) exhibits a weak secondary intramolecular Au···H−C(sp3) interaction as a secondary ...

Bis(silylene)‐Mediated N═N Bond Scission of Diazo Compounds

Angewandte Chemie, EarlyView.
The carborane‐based bis(silylene) enables unprecedented N═N bond scission in diazodiarylmethanes. While xanthene‐ and aniline‐based scaffolds promote end‐on addition with partial N═N activation, the carborane‐based variant uniquely achieves complete N═N bond scission of Ar2C═N═N compounds, resulting in isolable disilicon nitride imino species.
