Abstract [en]

Mastery of dinitramide salts requires the intertwined use of compatibility testing, surface sensitive spectroscopy, and quantum chemical calculations. This chapter shows these combined approaches providing atomistic and fundamental understanding of the complex processes that govern the decomposition, reactivity, and in the end, usefulness of dinitramide-based materials. Polarized dinitramide anions residing on the surface of dinitramide salts are theoretically predicted to exist and to dramatically accelerate decomposition. Such structures have been observed on the outmost monolayers of ammonium dinitramide (ADN) crystals using surface sensitive vibrational spectroscopy. Stabilization of ADN is realized by hindering the polarization of such structures with surface-active stabilizing agents. The full mechanisms for the self-decomposition of solid-state ADN and potassium dinitramide (KDN) are presented. Radical decomposition intermediates stress the necessity of using anti-oxidants as stabilizers. The anomalous solid-state behavior that has been observed in several dinitramide salts is also discussed and explained. Finally, the use of the dinitramide moiety in synthesis is briefly reviewed, and several mechanisms for its reactions with various olefinic double bonds are discussed.
