- Synthesis of Tetranitrotoluenes
-
New synthetic routes to the three isomeric tetranitrotoluenes 1-3 are described, including the previously unreported 2,3,4,5-tetranitrotoluene (1).Methods include peroxydisulfuric acid oxidation of trinitrotoluidines and hypophosphorous acid reduction of

- Synthesis of Polynitro Compounds. Hexasubstituted Benzenes
-
The synthesis of the three isomeric aminotetranitrotoluenes by nitration of an appriopriate aminodinitrotoluene is presented, and the apparent ipso nitration of 4-amino-2,6-dinitrotoluene to give pentanitroaniline, is also discussed.The oxidation of the isomeric aminotetranitrotoluenes to pentanitrotoluene is described, as is the ammonolysis of pentanitroaniline and of pentanitrotoluene.

- Synthesis of Polynitrodiazophenols
-
The formation of diazophenols by nitration of suitably substituted anilines and rearrangement of the nitroaromatic nitramines so formed is presented.The scope of the reaction is discussed, and a mechanism for the nitramine/diazophenol rearrangement is proposed which is consistent with 15N-labeling experiments.

- Methods of preparing pentanitrotoluene
-
Pentanitrotoluene is prepared by a method which comprises preparing an amdinitrotoluene from a precursor of either TNT or 2,5-dinitro-3-methylbenzoic acid, nitrating the aminodinitrotoluene to produce a nitramine intermediate, converting the nitramine intermediate to an aminotetranitrotoluene and oxidizing the aminotetranitrotoluene with peroxydisulfuric acid to pentanitrotoluene. Pentanitrotoluene is an explosive.
