Heterobimetallic Janus Catalysts for the One‐Pot Synthesis of Polar‐Apolar Block Copolymers

Angewandte Chemie, EarlyView.
Heterobimetallic Janus catalysts act as bifunctional initiators, combining two distinct polymerisation mechanisms in one pot to deliver well‐defined apolar‐polar block copolymers. Combining Earth abundant Ti and Al catalysts for respective α‐olefin and lactone polymerisation, the orthogonal activity is enabled by unprecedented initiation from a Ti ...

A de‐novo Approach Towards Divergent [3+2π/σ] Photocycloadditions of Nitrones via Assembly‐Controlled Kinetic Electron Transfer Gating

Angewandte Chemie, EarlyView.
A metal‐free photocatalytic platform converts nitrones into 4‐isoxazolines and oxa–aza–bicycloheptanes through divergent [3+2π/σ] cycloadditions. Assembly‐controlled kinetic electron transfer gating dictates substrate activation, enabling selective reactivity beyond thermodynamic expectations.

A Mesoionic Platform for Persistent Anionic Nitrogen‐Centered Radicals

Angewandte Chemie, EarlyView.
Charge did not meet spin: Mesoionic 1,2,3‐triazines undergo reversible one‐electron reduction to persistent anionic nitrogen‐centered radicals. Electron paramagnetic resonance, single‐crystal x‐ray diffraction, and calculations reveal nitrogen‐localized spin and structural reorganization, while crystalline salts show clean redox cycling.

Mechanistische Diversität in der photoangeregten Radikal‐Redoxchemie: Eine kritische Evaluierung

Angewandte Chemie, EarlyView.
Für viele prominente Beispiele der Photoredox‐Katalyse wird angenommen, dass sie über die Anregung einer offenschaligen („open‐shell“) Zwischenform des Katalysators ablaufen. Es wird jedoch intensiv darüber diskutiert, ob solche Mechanismen realistisch sind und, falls ja, wie genau sie ablaufen können.
