Abstract

Hydrogen peroxide in sulfuric acid oxidized 5-nitrobenzofuroxan into 1,2,4-trinitrobenzene and completed the oxidation of a mixture from benzodifuroxan and hydrogen peroxide in polyphosphoric acid into 1,2,3,4-tetranitrobenzene. The incompletely oxidized mixture also contained 4,7-dinitrobenzofurazan, a terminal oxidation product. Benzotrifuroxan was unreactive toward peroxidation.
