Monopersulfuric acid, trifluoroperacetic acid and hydrogen peroxide in polyphosphonic acid, or with selenium dioxide in t-butyl alcohol, or in tetramethylene sulfone have each oxidized benzofuroxan into o-dinitrobenzene.Monopersulfuric acid oxidized 4-nitrobenzofuroxan into 1,2,3-trinitrobenzene (80percent) and 4,6-dinitrobenzofuroxan into 1,2,3,5-tetranitrobenzene (99percent); hydrogen peroxide in polyphosphoric acid was moderately efficient for the latter oxidation.Copper in acidified ethanol transformed 4,6-dinitrobenzofuroxan into picramide quantitatively.
