SYNTHESIS OF POLYAZAPOLYCYCLIC CAGED POLYNITRAMINES

Syntheses of new polyazapolycyclic caged polynitramines are described. Sequentially reacting 4, 10-dibenzyl-2,6,8, 12-tetraacetyl-2,4,6,8, 1 0,12-hexaazaisowurtzitane (5a) with NOBF4 and NO2BF4 in sulfolane solv ent produces 2,4,6,8,10,12-hexanitro-2,4,6,8, 10, 12-hexaazaisowurtzit ane -hexaazatetracyclo-[5.5.0.0(5,9).0(3,11)]dodecane, 6). Syntheses o f two new polyazapolycyclic caged trinitramines, 3,5,12-trinitro-3,5,1 2-triazawurtzitane (7a) and 2,4,10-trinitro-2,4, 10-triazaadamantane ( 12a), as well as their labile parent secondary amines, are discussed. A new caged polynitrosamine, 3,5,12-trinitroso-3,5,12-triazawurtzitane (7d), has been obtained by ring-cleavage nitrosation of the new hexam ine-wurtzitane compound o-[9.3.1.1(3,7).0(2,9).0(4,13).0(5,10)]-hexade cane (10).
