experimental part, p. 2058 - 2062 (2011/01/08)
An efficient explosion-proof method was developed for the preparation of N,N-dialkylnitramines by treatment of dialkylammonium nitrates with a mixture of nitric acid and acetic anhydride in the presence of ZnCl2 in liduid or supercritical carbon dioxide.
Clean nitrations: Novel syntheses of nitramines and nitrate esters by nitrodesilylation reactions using dinitrogen pentoxide (N2O5)

In this novel nitration method dinitrogen pentoxide (N2O5) in an inert solvent is used as the nitrating agent, thereby removing the need for strong acids as the reaction medium. The N2O5 cleaves heteroatom-silicon bonds, in silylamines and silyl ethers respectively, to yield the desired energetic groupings (nitramines or nitrate esters respectively) without liberation of acids which would occur with conventional substrates (amines or alcohols). These nitrodesilylation reactions proceed cleanly and in good yield, and the scope of the reaction is illustrated by 29 examples, some of which produce high energy compounds, notably plasticisers and an energetic polymer precursor. These reactions are therefore potentially clean nitrations for the manufacture of energetic compounds which will minimise the impact of this activity on the environment in the future.

The rate of the reaction of methyl-N,N-dinitroamine with a series of dialkylamines, which occurs through a stage of electron transfer with the formation of dialkyl-N-nitroamines and salts of methyl-N-nitroamine, was measured by a spectrophotometric method in acetonitrile at 15-45 deg C.The reaction has first order in each of the reagents.An isokinetic relationship is observed in the reaction series, β=38819 deg K.The effect of the structure of the amine on the rate of the process is described by the Swain-Scott and Taft equations.The low value of the reaction constant ρ* in the last equation (0.99-1.60) shows that the transition state of the reaction has low polarity.
