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. In particular, mono- and bis-(difluoroaminomethyl) oxetanes are synthesized and further reacted to yield the corresponding dinitrate esters. It has been discovered that these NF.sub.2 -dinitrate esters are very useful as energetic plasticizers in high-energy formulations.
