The benzophenone-sensitized photolysis of the title hydroxylamine (1) in hexadecyltrimethylammonium chloride (HTAC) micelles was found to give benzoyloxy(2,3)- and phenyl(4,5)-migrated products, along with fragmentation products, 1-naphthanilide (6) and b

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.
