Advanced Synthesis &Catalysis, EarlyView.A dual photocatalytic system of o‐PQ and Sn(OTf)2 enables visible light‐induced Mannich‐type addition of ethers to nitrones via Csp³–H activation. This oxidant‐free method offers broad scope and good yields. Mechanistic studies suggest that a photoexcited o‐PQ–Sn(II) complex mediates hydrogen atom transfer to form α‐oxy radicals for nitrone addition. A

Advanced Synthesis &Catalysis, EarlyView.A nickel catalyzed electrochemical cross‐electrophile coupling approach for the base‐free synthesis of (un)symmetric (hetero)aryl and alkyl sulfides from organic halides and disulfides is described. The reaction is broadly applicable and tolerates water and air atmosphere. A formal cross‐electrophile coupling approach enables the base‐free synthesis of

Photoredox‐Catalyzed Synthesis of a Novel Class of Fluoroalkyl Pyrazolones
Advanced Synthesis &Catalysis, EarlyView.A photoredox strategy enables regioselective synthesis of fluoroalkyl 2‐pyrazolin‐5‐ones via radical addition and cyclization. This mild, metal‐free method shows a broad substrate scope, operates in batch and flow systems, and offers a sustainable approach to fluorinated heterocycles with potential applications in medicinal chemistry.

Recent Advances in Ene Reactions with Carbon Enophiles
Advanced Synthesis &Catalysis, EarlyView.Recent advances in the classical intra‐ and intermolecular ene nexus with carbon enophiles (alkenes, alkynes, arynes, and allenes) show a considerable increase in structural complexity and an enormous potential for functional applications in polymer science.

Advanced Synthesis &Catalysis, EarlyView.A mild, scalable electrocatalytic method for direct lactonization of benzylic alcohols to phthalides using N‐hydroxyphthalimide as a redox mediator is reported. This metal‐free process proceeds via a phthalimide‐N‐oxyl‐mediated hydrogen atom transfer mechanism, shows broad scope with good to excellent yields, and enables late‐stage functionalizations ...
