Fe‐Photocatalyzed Decarboxylative Giese‐Type Reaction of α‐N, O or S Carboxylic Acids: Insight into the Mechanism of the Radical Formation

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Electron‐deficient alkenes can be functionalized with α‐amino, α‐alkoxy and α‐alkylthio radicals formed by Fe‐photocatalyzed decarboxylation of the corresponding carboxylic acids. The reactions proceed under smooth ligandless conditions with inexpensive base and in the absence of oxidant. A mechanistic computational TD‐DFT study supports the occurrence

Thioether Synthesis via the Nickel‐Catalyzed Electrochemical Cross Electrophile Coupling of Aryl/Alkyl Disulfides and Aryl/Alkyl Halides

open access: yesAdvanced 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

Recent Advances in Ene Reactions with Carbon Enophiles

open access: yesAdvanced 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.

Visible‐Light Photocatalyzed Selective Synthesis of 1,2‐ or 1,3‐Dithianes From Thietanes: An Experimental and Theoretical Study

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Although this article formally presents a regioselective photochemical ring enlargement of thietanes into 1,2‐ or 1,3‐dithianes, time‐dependent density functional theory calculations have revealed that 1,3‐dithianes are in fact formed thought photoinduced hydrogen atom transfers from 1,2‐dithianes initially resulting from the ring enlargement using ...
