A kinetic study on the base-catalyzed acyl group-exchange reactions of N,O-diacyl-o-aminophenols was undertaken to show that the formation of the amidate ion should be the rate-determining step in these intramolecular acyl exchange reactions, and that the

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.

The photodecomposition of the title compounds yielded the rearrangement products derived from 1,3- and 1,5-aroyloxy migrations in addition to the fragmentation products typical of the aroyloxyl and amido free radicals.Crossover experiments indicate an int
