Herein, we present an overview of recent advances in the electrochemical halogenation of organic compounds. Halogen-containing compounds are essential building blocks for post-functionalization in academic research and in different industrial...

An efficient copper‐catalyzed three‐component chalcogenation of oxadiazoles with elemental selenium/sulfur and aryl iodide is described herein. This one‐pot C(sp2)‐H bond chalcogenation approach is attractive and practical, since a cheap copper catalyst is employed with minimum catalytic loading, in an open‐to‐air atmosphere. Under optimized conditions, that reaction provides a wide range of structurally diverse organochalcogenyl (Se/S)‐oxadiazoles in good to excellent yields with good functional group tolerance. This practical approach represents a valuable contribution to synthetic and medicinal chemistry, providing an important addition to the current C−Se/S bond formation chemistry scenario.

Herein, we report an eco-friendly, electrosynthetic approach for the intramolecular oxyselenylation of allyl-naphthol/phenol derivatives.

Herein, a greener approach to the eosin Y‐Na2 catalyzed, C(sp2)−H bond azo coupling of imidazoheteroarene with aryl diazonium salts is described, under acid free conditions. This direct photoredox process resulted in the corresponding azo products in good to excellent yields. Besides, this new approach could also be applicable to anilines, which is a poorly reactive substrate by other methods. The main features of this reaction are that it provides high yields and is gram‐scalable and applicable to biologically relevant imidazoheteroarenes and ‐anilines.
