Novel energetic compounds are provided comprising N,N'-azobis-nitroazoles or analogs thereof. The compounds are useful as igniter materials in a variety of energetic compositions, particularly gas-generating compositions for inflating automobile or aircraft occupant restraint devices. The compounds are also useful in solid rocket propellant compositions, and as primary explosives to be used as detonators, blasting caps, firearms, and the like. Methods for synthesizing the compounds and manufacturing energetic compositions herewith are provided as well.
[ We claim:] [1.] A compound having the structural formula (I) [ STR 13 ] wherein: R is a monocyclic nitrogen-containing heterocycle or a bicyclic aromatic substituent;R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are independently selected from the group consisting of N, N.fwdarw.O, (N.sup.+ --R.sup.a)Z.sup.-, CH, C--R.sup.b, C--NR.sup.c R.sup.d, and C--NO.sub.2 in which R.sup.a and R.sup.b are independently C.sub.1 -C.sub.24 alkyl, or fluoro, R.sup.c and R.sup.d are independently H or C.sub.1 -C.sub.24 alkyl, and Z.sup.- is a counterion, or wherein R.sup.4 is ...
