Abstract

Based on the e.s.r. identified nitroxyl radicals 4,5, and 6 produced in organic solvent, a radical mechanism in the photoreaction of some paradiazine N,N-dioxides was suggested. The intermediate radicals 8 were produced , in the photoreduction process such as deoxygenation and hydrogen abstraction, from either triplet excited state or from diradicals 7.
