Deconstructive Radical–Radical Coupling for Programmable Remote Acylation

Angewandte Chemie, EarlyView.
A unified approach to access a variety of 1,n‐dicarbonyls through a radical‐promoted deconstructive process utilizing dual photocatalysis/carbene catalysis is reported. The utility of this strategy is demonstrated with a broad scope with robust functional group tolerance along with application in the preparation of γ‐amino esters, three‐component ...

On‐Demand Photodegradable and Thermo‐Reversible, Soft, Transparent Dithioacetal Hydrogels

Angewandte Chemie, EarlyView.
A versatile chemical platform for the development of photodegradable and thermally–reversible hydrogels is presented. The hydrogels were synthesized via a step‐growth reaction of a difunctional PEG‐thiol with an aromatic dialdehyde cross‐linker. The photosensitive dithioacetal bonds endowed the material with photodegradable and thermo‐reversible ...

An Atomically Dispersed Photocatalyst for Undirected para‐Selective C─H Bond Functionalizations

Angewandte Chemie, EarlyView.
This study presents an atomically dispersed recyclable heterogeneous photocatalytic method for para‐selective trifluoromethylation of electron‐deficient arenes without directing groups. Unlike previous substrate‐dependent approaches, this recyclable, atomically dispersed photocatalyst enables scalable synthesis of bioactive trifluoromethylated ...

Direct Activation of Sulfides by C–H Oxidation with Photoexcited Nitroarenes: Formal Manipulations of the C─S Bond

Angewandte Chemie, EarlyView.
Photochemical anaerobic oxidation of sulfides, using nitroarenes as bifunctional reagents, enables the formal manipulation of the C─S bond. The method allows direct and selective access to versatile carbonyl compounds from largely inert sulfides by C–H oxidation, thus avoiding multistep activation by sulfur oxidation.
