Paragraph 0047-0048, (2020/01/12)
An economic, one-step method for the production of N-substituted aromatic hydroxylamines of formula (I) [in-line-formulae]R—N(OH)—C(═O)—(O)R1??(I),[/in-line-formulae] with hydrogen, by catalytic hydration with possibly modified hydration catalysts in an aprotic solvent and in the presence of a halogen formic acid ester and in some cases in the presence of a base.

A copper-catalyzed ketooxygenation of electron-deficient alkenes was developed. This approach combines O-H alkylation, aerobic decarboxylation, and oxygenation in one transformation. Mechanistic investigation of this reaction showed that the copper salt is responsible for both generating the amidoxyl radical and promoting aerobic decarboxylation.

supporting information; experimental part, p. 13320 - 13322 (2011/10/10)
The dioxygenation of alkenes using molecular oxygen and a simple hydroxamic acid derivative has been achieved. The reaction system consists of readily prepared methyl N-hydroxy-N-phenylcarbamate and molecular oxygen with a radical initiator, offering an alternative to common dioxygenation processes catalyzed by precious transition metals. This transformation capitalizes on the unique reactivity profile of hydroxamic acid derivatives in radical-mediated alkene addition processes.

A formal synthesis of (±)-eseroline via an azaoxy-cope rearrangement
Santos, Paulo F.,Almeida, Paulo S.,Lobo, Ana M.,Prabhakar, Sundaresan
, p. 1029 - 1043 (2007/10/03)
A novel synthesis of (±)-desoxyeseroline, from the crucial oxindole (15), obtained by a 3,3-sigmatropic rearrangement of the enolate derived from the hydroxamic acid derivative (5) followed by radical desulfurisation, has been described. The requisite Cs
