Abstract: This invention relates to novel neopentyl difluoroamino compounds which are useful as plasticizers and oxidizers in energetic formulations, such as propellants, explosives, and gasifiers. These neopentyl difluoroamino compounds can be prepared either: (1) by the direct fluorination of amine derivatives containing energetic pendant groups; or (2) by first preparing NF.sub.2 -derivatives and then substituting these derivatives with energetic pendant groups.

It has been discovered that these NF.sub.2 -dinitrate esters are very useful as energetic plasticizers in high-energy formulations.

Abstract: Nitric oxide has proved to mediate many important physiological processes. The nitric oxide donors of the present invention have a NONOate anion linked to an ortho-substituted aryl, a heteroaromatic substituent, asteroid, or a catecholamine. Preferred ortho substituents are alkoxy, halo, and alkyl. The cation of the salt is an alkali metal, an alkaline-earth metal, an ammonium or substituted ammonium group. Nitric oxide donors provided herein are more stable than that of nitrogen-bonded NONOates described previously. The by product left after release of NO, and the nitric oxide donors themselves, are very probably less carcinogenic than the corresponding nitrogen-bonded NONOates.
