Ammonium salts with oxidizing anions decompositions

A common feature of the decompositions of many ammonium compounds is the identification of the first step in reaction as proton transfer. The consequent accumulation of protons with the residual oxy-anions may be followed by the elimination of water, accompanied by condensation (or continued condensation) of the anions, see chromates and phosphates above, ultimately leading to residual oxide formation. Alternatively the acid may be volatilized, many ammonium salts sublime... 

Quaternary ammonium salts exhibit high catalytic activity in radical-chain reactions of hydrocarbons liquid phase oxidation by [1, 2]. Tetraalkylammonium halides accelerate radical decomposition of hydroperoxides [3,4] that are primary molecular products of hydrocarbons oxidation reaction. Reaction rate of the hydroperoxides decomposition in the presence of quaternary ammonium salts is determined by the nature of the salt anion [4] as well as cation [5]. The highest reaction rate of the tert-butyl hydroperoxide and cumene hydroperoxide decomposition has been observed in the case of iodide anions as compared with bromide and chloride ones [4]. tetraalkylammonium bromides tetraethylammonium...
