Abstract
Novel compounds are provided having the structural formula R[—N(NO2)—L—R1]n wherein R, L, R1 and n are defined herein. The compounds are useful in a variety of contexts, but are primarily to be used as high energy oxidizing agents in explosive compositions, propellant formulations, gas-generating compositions and the like. The compounds are also useful as pharmaceutical agents. Compositions containing the compounds are also provided, including energetic compositions, as are methods for using the novel compounds and compositions.
Claims42
A compound having the structural formula (I)
- wherein:
- R is either (a) C4-C24 hydrocarbyl substituted with 1 to 6 —L—R1 substituents or (b) —L—R1;
- L comprises a divalent hydrocarbylene linking group;
- R1 is selected from the group consisting of
- wherein R15 through R26 are independently selected from the group consisting of N, N→O, (N−—Ra)Z−, CH, C—Rb, C—NRcRd, and C—NO2 in which Ra and Rb are independently C1-C24 alkyl or fluoro, Rc and Rd are independently H or C1-C24 alkyl, Y− is an oxidizing anion or a nitrogen-containing heterocyclic anion, J is C or N, and x is zero or 1;
- n is an integer in the range of 1 to nmax, wherein nmax is the maximum number of —N(NO2)—L—R1 groups that can bind to R through single covalent bonds.
A compound having the structural formula (I)
- wherein:
- R is polymeric;
- L comprises a divalent hydrocarbylene linking group;
- R1 is selected from the group consisting of monocyclic five-membered nitrogen-containing heterocycles and bicyclic nitrogen-containing heterocycles comprised of two five-membered rings or one five-membered ring and one six-membered ring, optionally substituted with one through four substituents per ring, wherein the substituents are selected from the group consisting of amino, alkylamino, dialkylamino, halogenated amino, nitro, alkyl and halogen;
- and
- n is an integer defining the number of —N(NO2)—L—R1 groups bound to R.
