Trimethylammonium nitrate

Radicals seem to be intermediates in the cleavage this is in accordance with the fact that a mixture of meso- and d,h 7-2,2-diphenylbutane is foraied in the electrolysis of chiral Z)-Q -phenylethyl-l-trimethylammonium nitrate in DMF [172] and that ESR spectroscopy reveals the presence of radical fragments in the reduction of dimethylbenzylanilinium salts [173].

Kinetic data are available for the nitration of a series of p-alkylphenyl trimethylammonium ions over a range of acidities in sulphuric acid. - The following table shows how p-methyl and p-tert-h xty augment the reactivity of the position ortho to them. Comparison with table 9.1 shows how very much more powerfully both the methyl and the tert-butyl group assist substitution into these strongly deactivated cations than they do at the o-positions in toluene and ferf-butylbenzene. Analysis of these results, and comparison with those for chlorination and bromination, shows that even in these highly deactivated cations, as in the nitration of alkylbenzenes ( 9.1.1), the alkyl groups still release electrons in the inductive order. In view of the comparisons just...

The salt has a heat of expln of 834kcal/kg and a vol of deton gases of 1102 /kg. Its energy of formation is —562 kcal/kg, and enthalpy of formation is —598 kcal/kg. The salt is not stable when stored, above 150° and may become auto-catalytically accelerated into an expln because of the progressive prodn of nitric oxide from the liberated nitric acid (Ref 2)...
