Domino Polymerization for the Synthesis of Reductively Degradable Poly(disulfide)s With Arbitrary Side‐Chain Structures

Angewandte Chemie, EarlyView.
We developed a novel domino polymerization to synthesize reductively degradable poly(disulfide)s with tunable side chains. A novel monomer bearing thiolactone and pyridyl disulfide groups reacts with various amines, enabling continuous ring‐opening and disulfide exchange.

Alkoxysulfonium Salts Unlock Access to New Aryl Sulfonium Salts for Cross‐Coupling

Angewandte Chemie, EarlyView.
Hard‐to‐access (hetero)aryl sulfonium salts are prepared using stable methoxysulfonium salts in combination with the magnesiation of (hetero)aryl bromides. The approach allows access to aryl sulfonium salts bearing electron‐deficient (hetero)aryl rings, or electron‐rich aryl motifs in which the sulfonium motif resides at an alternative position on the ...

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
