Anion‐Controlled Structural Interconversion of Palladium Cages Enables Separations by Selective Guest Capture and Release

Angewandte Chemie, EarlyView.
We report a pair of interconvertible palladium(II) cages assembled from an asymmetric ligand, whose switching is triggered by specific counter‐anions, tetrafluoroborate (BF4−) and bis(trifluoromethanesulfonyl)imide (NTf2−). Their complementary guest preferences enable orthogonal, multi‐cycle catch‐and‐release, exemplified by the selective purification ...

Aryl and Alkyl Radiotrifluoromethylation via Metallaphotoredox‐Mediated Radical Cross‐Coupling

Angewandte Chemie, EarlyView.
The metallaphotoredox‐mediated radiotrifluoromethylation of arenes and alkanes is described. The operationally simple protocols make use of substrates bearing thianthrenium salts (TT) or N‐hydroxyphthalimide (NHPI) esters and CF218FI. The reaction proceeds through a Ru‐mediated radical formation followed by a Cu‐mediated radical cross‐coupling step and

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.

Depolymerization and Reuse of Polycarbonates: Emerging Classes, Mechanisms and Challenges

Angewandte Chemie, EarlyView.
This review collects the latest developments in the area of chemical and catalytic polycarbonate recycling strategies and includes the controlled degradation of similar types of macromolecules. Apart from the main strategies for deconstruction, the key mechanistic features of these depolymerization processes are also discussed together with the ...
