Abstract

A method is described for the preparation of o-quinone dioximes from the reaction of benzofurazan oxide (or its congeners) with sodium dithionite, thiophenols, phenylhydroxylamine, and hydrazine derivatives. These, and other related reactions reported in the literature, are interpreted as two-electron transfer processes from reductant to benzofurazan oxide (oxidant), leading to the o-quinone dioxime anion.
