1. A method, comprising: exposing a bis-oxadiazole product to a nitrating agent to provide a bis-oxadiazole dinitrate, wherein the bis-oxadiazole product has a structure of a formula
wherein each Y independently is aliphatic-OH or aliphatic-OPG, wherein PG is a hydroxyl protecting group and the nitrating agent is HNO 3 .
2. The method of claim 1 , further comprising making the bis-oxadiazole product by combining a diaminoglyoxime product with a carbonyl-containing reagent and a solvent to form a reaction mixture and heating the reaction mixture at a temperature above room temperature.
3. The method of claim 2 , wherein the diaminoglyoxime product has a structure
the carbonyl-containing reagent has a structure of a formula
wherein Z is alkoxy or halogen and Y is aliphatic-OH or aliphatic-OPG, wherein PG is a hydroxyl protecting group, and the solvent is a mixture of DMF and toluene, or a dioxane solvent, or acetonitrile.
4. The method of claim 3 , wherein the method further comprises making the diaminoglyoxime product by combining a di-aldehyde precursor compound with a hydroxylamine.
5. The method of claim 4 , wherein the di-aldehyde precursor compound is oxalaldehyde and the hydroxylamine is NH 2 OH, or an aqueous composition thereof.
