Energetic candidate azido heterocycles and their synthesis are described.

Synthesis of azido heterocycles

A method for synthesizing pentanitrohexaazaisowurtzintane under neutral reaction conditions. Which synthesis involves treating a solution of hexanitrohexaazaisowurtzitane in ethyl acetate in the presence of a catalytic quantity of palladium on a carbon substrate, until a heterogeneous mixture is formed. This heterogeneous mixture is hydrogenated under a balloon atmosphere until the starting hexanitrohexaazaisowurtzitane is substantially reacted. The resulting pentanitrohexaazaisowurzitane mixture is filtered, dried and recovered from the dried residue through a Si-gel column.

Hydrogenolytic denitration of polynitro compounds: pentanitrohexaazaisowurtzitane

The invention is a composition containing high loadings of TNAZ that are made by crash precipitation with water as the precipitation agent. The compositions are in the form of powders, which can be formed and shaped by presseing, extrusion, etc. The TNAZ can be from about 94 to about 99% by weight of the composition.

1,3,5,7-Tetraacetyloctahydro-1,3,5,7-tetrazocine is produced in improved ld by reacting 1,5-diacetyl-1,3,5,7-tetraazabicyclo-[3.3.1]-nonane with acetic anhydride in the presence of a metal acetate, such as sodium acetate.
