Chemistry of hydroxamic acid XII: Photochemistry of N-phenylbenzenecarbo-hydroxamic acid—studies on the mechanism of reaction

Abstract

The quantum yield for the photodestruction of N-phenylbenzenecarbohydroxamic acid was determined in a number of solvents. Protonation was found to photostabilize both the hydroxamic acid and its anion. Quenching studies showed that the reaction in cyclohexane occurs from both the singlet and the triplet state, giving benzanilide as the main photoproduct. The results are discussed in the light of other recent investigations in the field.
