A photoactivatedneutralorganic super electrondonor cleaves challenging arenesulfonamides derived from dialkylamines at room temperature. It also cleaves a) ArCNR and b) ArNCbonds. This study also highlights the assistance given to these cleavage reactions by the groups attached to N in (a) and to C in (b), by lowering LUMO energies and by stabilizing the products of fragmentation.
光活化的中性有机超电子供体在室温下裂解衍生自二烷基胺的具有挑战性的芳烃磺酰胺。它还裂解 a) ArC NR 和 b) ArN C 键。该研究还强调了通过降低 LUMO 能量和稳定碎裂产物,连接到 (a) 中的 N 和连接到 (b) 中的 C 的基团对这些裂解反应的帮助。

Se-Phenyl benzoselenohydroximate derivatives, which are prepared from stable and readily available Se-phenyl benzoselenohydroximate, are useful radical precursors for the generation of alkyl, aminyl, and alkoxy radicals.

The first crown-tetracarbene complex of Ni(II) has been prepared, and its crystal structure determined. The complex can be reduced by Na/Hg, with an uptake of two electrons. The reduced complex reductively cleaves arenesulfonamides, including those derived from secondary aliphatic amines, and effects Birch reduction of anthracenes as well as reductive cleavage of stilbene oxides. Computational studies show that the orbital that receives electrons upon reduction of the complex 2 is predominantly based on the crown carbene ligand and also that the HOMO of the parent complex 2 is based on the ligand.
