This is a rough idea for a synthetic route to pyrrolo[2,1-c]-1,2,3-triazole derivitives. This ring system is similar to
3,6-Dinitropyrazolo[4,3-c]pyrazole (DNPP), which has already been synthesized and studied, except the nitrogens are in the center. This configuration should allow more powerful derivitives for two reasons. First, there are two less C--N bonds, since the nitrogen chain is continuous. Compounds with more N--N bonds tend to be more energetic. Second, none of the carbons are between the rings, so all four carbons are available to bond to other functional groups (typically nitro or amino). While amino groups have been experimentally added to the nitrogen atoms of
DNPP, such a compound was roughly twice as sensitive as HMX, and had unexpectedly lower density because the amino groups were not planar with respect to the remainder of the molecule.
(The addition of amino groups to the nitrogen atoms did make the molecule more powerful, hower; roughly 5% more than HMX).
The picture should be seen more as containing rough ideas to possibly inspire a more refined route which could work.
Any comments or suggestions are welcome.
