Abstract
The oxidation of secondary and tertiaryα-hydroxylamino oximes with sodium hypobromite gives, respectively, furoxans and 3-bromo-1,2-diazetine 1,2-dioxides. The intermediate oxidation products, which confirm the proposed reaction mechanism, were isolated. When 3-bromo-1,2-diazetine 1,2-dioxides are heated in benzene, the ring opens with the evolution of nitrogen oxides and the formation of halo olefins.
