Contrary to C–H chlorination and bromination, the direct iodination of alkanes represents a great challenge. We reveal a new N-iodoamide that is capable of a direct and efficient C–H bond iodination of various cyclic and acyclic alkanes providing iodoalkanes in good yields. This is the first use of N-iodoamide for C–H bond iodination. The method also works well for benzylic C–H bonds, thereby constituting

日期:——
The highly symmetrical quartet triradical trimethylenebenzene has been isolated for the first time (see structure). Despite its open‐shell character, it was photochemically stable and this makes it a promising building block for magnetic materials.

azaarenes with alkyl iodines has been established through strategic modulation of N- or P-donor ligands. This method enables the synthesis of diverse β- or γ-branched aromatic N-heterocycles. The mild regiodivergent protocols exhibit wide substrate scope, excellent functional tolerance, and great reaction yield with remarkable regioselectivity. Importantly, deuterium labeling studies reveal NiH-catalyzed
