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.
Claims21
A compound having the structural formula (I)
- wherein:
- R is either (a) C4-C24 hydrocarbyl substituted with zero to 6 substituents and optionally containing one or more non-hydrocarbyl linkages and one or more nonhydrogen, noncarbon atoms, or (b) —L—R1, or (c) polymeric;
- L comprises a divalent hydrocarbylene linking group;
- R1 is —ONR2R3, —O—[NR2R3R4]+Y−, —ON═CR5R6 or —O—[N═CR5R6]H+Y− wherein R2, R3 and R4 are independently hydrogen, alkyl, aryl, or aralkyl, if alkyl, aryl or aralkyl, optionally substituted with —NO2, —NH2 and/or —NF2 substituents, Y− is an oxidizing anion or a nitrogen-containing heterocyclic anion, and R5 and R6 are independently H, —NH2, —NF2, —NR7—NH2 or —NR7(NO2) wherein R7 is hydrogen, alkyl, aryl, aralkyl, if alkyl, aryl or aralalkyl, optionally substituted with —NO2, —NH2 and/or —NF2 substituents;
- and
- 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.
