Hexabenzylhexaazaisowurtzitane is converted to tetracetyl, dibenzyl azaisowurtzitane. The benzyl groups are removed by catalytic transfer hydrogenolysis leaving a pair of available nitrogens. The available nitrogens are acetylated, and the resulting intermediate is converted to CL-20 with a strong nitrating agent.

What is claimed is: 1. A compound selected from the group consisting of wherein each of the "R's" is the same or different and is selected from the group consisting of alkyl, cycloalkyl, aryl, arylalkyl, alkene, alkyne, substituted forms of any of these groups, and H, and wherein a group consisti
What is claimed is: 1. A compound selected from the group consisting of wherein each of the "R's" is the same or different and is selected from the group consisting of alkyl, cycloalkyl, aryl, arylalkyl, alkene, alkyne, substituted forms of any of these groups, and H, and wherein a group consisting of a hydrogen ion (H+) and a complementary anion is present on neither, one, or both of the nitrogens in the 4 and 10 positions. 2. The compound of claim 1, wherein the compound is formula (IV). 3. The compound of claim 2 wherein all R's are CH3. 4. The compound of claim 1 wherein the compound is formula (V) . 5. The compound of claim 4 wherein the compound comprises a hydrogen ion and an anion associated with the nitrogen in each of the 4 and 10 positions, the anion being an energetic anion. 6. The compound of claim 5 wherein the anion is NO3 - or ClO4-. 7. The compound of claim 1 wherein the compound is formula (VI) and wherein all R's are CH3 or H. 8. A method of preparing a compound of formula IV: wherein each R is independently selected from the group consisting of alkyl, cycloalkyl, aryl, arylalkyl, alkene, alkyne, a substituted form of any of these groups, and H, and wherein a member from the group consisting of a hydrogen anion and a complementary anion is present on neither, one, or both of the nitrogens in the 4 and 10 positions, the method comprising: hydrogenolyzing a compound of formula III: 9. The compound of claim 2, wherein the compound is represented by the formula: 10. The compound of claim 2, wherein the compound has a group consisting of a hydrogen atom and a complementary anion associated with the nitrogen in each of the 4 or 10 positions. 11. The compound of claim 2, wherein the compound has a group consisting of a hydrogen atom and a complementary anion associated with the nitrogen in each of the 4 and 10 positions. 12. The compound of claim 10, wherein the complementary anion is an energetic anion. 13. The compound of claim 11, wherein each complementary anion is an energetic anion. 14. The compound of claim 4, wherein the compound is represented by the formula: 15. The compound of claim 4, wherein the compound has a group consisting of a hydrogen atom and a complementary anion associated with the nitrogen at the 4 or 10 positions, and wherein each complementary anion is an energetic anion.
