Good idea BASF!


:D wow, from the big master. Let´s mark the day red in the calendar. ;)

Hmm, would the bromine change places with the nitro-group on the aza-function?

This would be bad... maybe one could attach a protective-group to the the aza-function, then halogenate then remove the protective-group and oxidize.

Arrrgh....how complicated this got again. :mad:

BTW, pat. GB 615793 mentions a linear nitramine with 3 nitro-groups on the aza-functions and 2 nitrate-groups at the ends of the chain. It has a MW over 400g/mol, despite this it performed very well in the Trauzl test(580ccm), and this at a density of 0.7g/ccm...

Not a big surprise then, this simple molecule with OB near zero is sensitive as hell(3 times more sensitive than PETN)...

Maybe stabilization via hydrogen-bonding? - What if one would replace two of the nitro-groups with 2 -NH2-functions instead of it ....

A nice link

So you can make sodium tetrazolide by reacting hydrogen cyanide and sodium azide. To get 1-nitrotetrazole, react this with a nitryl salt. And to get 1-azido-5-nitrotetrazole, do the above mentioned procedure but use cyanogen chloride (if you dare :cool: ) or, alternately, use chlorazide and hydrogen cyanide and then react with a nitryl salt or use straight nitryl cyanide, then react your product with sodium azide.
To get 5-azido-1-nitrotetrazole, use cyanogen azide and hydrazoc acid, then react with a nitryl salt.
Both of these compounds have perfect OB and presumably VoDs, as 5-nitrotetrazole has a VoD of more than 8.5 km/s.
