Decomposition mechanism of dinitramide onium salts

Article abstract of DOI:10.1007/BF02503770

Thermal decomposition of dinitramide onium salts proceeds via the dissociative mechanism when pK_a of the base is lower than 5.0 and via the monomolecular decay of the anion at pK_a > 7.0. On going from the melt to the solid state, the reaction mechanism does not change, and the rate decreases by 1-2 orders of magnitude. No anomalous effects inherent in dinitramide metal salts in the solid phase are observed during decomposition of onium salts.
