2,2'-Bipyridyl N,N'-dioxide, its derivatives substituted at the 4- and/or 4'-positions by methoxy, nitro, chloro, and bromo groups, and the corresponding N,N'-deoxygenated compounds have been synthesized.The N,N'-dioxides were examined in a number of refluxing solvents and under sublimation to investigate a potential liberation of singlet oxygen.All N,N'-dioxides were found to be stable under such conditions with no production of the corresponding N,N'-deoxygenated compounds.
