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.

The recovery and separation of plutonium(IV) and americium(III) by solid-phase extraction (SPE) on alkylated silica gel S16 modified with N-benzoylphenylhydroxylamine (BPHA) and with its derivatives was studied. BPHA was modified by introducing into the p-position of the phenyl ring of electronactive substituents that differ in their hydrophobicity: CH3, Ph, Cl, F, and NO2. The SPE of plutonium(IV) and americium(III) was studied in the range of acidities from pH 8 to 1 M HNO3. The recovery and separation of these elements was shown to depend on the nature of the substituent, aqueous acidity, and the preparation of S16 to SPE experiments.

The photochemical decomposition of the title compounds yielded the rearrangement products derived from 1,3- and 1,5-aroyloxyl migrations in addition to the fragmentation products typical of the aroyloxyl and amido radicals, while only 1,3-aroyloxyl migration was observed on thermolysis.The results of crossover experiments indicate an intramolecular rearrangement, probably involving homolysis of the N-O bond in the excited states.Triplet quenching studies demonstrate that the rearrangement and fragmentation proceed exclusively via the first excited singlet state.No formation of the rearrangement products on triplet sensitization was expl ained on the basis of the spin multiplicity effects on a radical-radical recombination process within a solvent cage.
