The synthesis of the polynitroaromatic compound pentanitrobenzene was re-examined by modern spectroscopic, structural and physicochemical methods. Originally prepared in 1979, this material could exhibit interesting properties as an oxygen-rich energetic building block. The energies of formation were calculated with the GAUSSIAN program package and the detonation parameters were predicted using the EXPLO5 computer code. The performance data were determined and compared to the common oxidizer ammonium perchlorate. The crystal structure of pentanitrobenzene was determined by X-ray crystallography, and those of 2,3,4,6-tetranitroaniline and styphnic acid (trinitroresorcinol) were re-determined.

Peroxydisulfuric acid in sulfuric acid solution, prepared by reaction of hydrogen peroxide with excess oleum or 100percent H2SO4, oxidizes primary polynitroarylamines and their N-acetamido derivatives to polynitro aromatics in good to excellent yields.The new procedure is illustrated by the synthesis of several new polynitro compounds, not preparable by known synthetic methods.Peroxytrifluoromethanesulfonic acid is comparably efficient for such oxidations.The scope and limitations of the new reaction have been examined and compared to other methods of synthesis of polynitro compounds.
