An efficient one‐pot synthesis of hydroxamicacids from aldehydes and hydroxylamine is described. A fast, visible‐light‐mediated metal‐free hydroacylation of dialkyl azodicarboxylates was used to develop the subsequent addition of hydroxylamine hydrochloride. A range of aliphatic and aromatic aldehydes were employed in this reaction to give hydroxamicacids in high to excellent yields. Application

amidation of unactivated alkenes. Due to the preference for five-membered nickelacycle formation, the chain-walking isomerization initiated by the NiH insertion to an alkene can be terminated at the γ-methylene site remote from the alkene moiety. By employing 2,9-dibutyl-1,10-phenanthroline (L4) as the ligand and dioxazolones as the reagent, the amidation occurs at the γ-C(sp3)–H bonds to afford the amide

N-Acyl nitrenes have been generated from a range of heterocyclic precursors, and their applications in light-inducedruthenium-catalyzedsulfurimidations have been studied. Analyzing the reaction scope and determining the structural requirements of the in situ formed electrophilic nitrogen species for effective nitrenetransfer allowed a mechanistic scheme to be proposed. The mechanistic conclusions
