1. The kinetics of the thermal decomposition of bis-(2,2-dinitropropyl)-N-nitrosoamine, bis-(2,2-dinitro-2-fluoroethyl)-N-nitrosoamine, and bis-(2,2,2-trinitroethyl)-N-nitrosoamine was studied. 2. The reactions are described by a first-order equation. The activation energies and preexponential factors were determined. 3. The reaction center in the bis-(2,2,2-trinitroethyl)-N-nitrosoamine molecule is the trinitromethyl group, while in the other two compounds it is the nitrosoamine group. The mechanism of the decomposition is discussed. 4. The enthalpy of formation of the (NO2)2CCH2N(NO)CH2C(NO2)3 radical was calculated.

1. The thermochemical characteristics were determined experimentally and the energies of the nitrogen-nitrogen bonds calculated for certain alkyl- and polynitroalkyl-N-nitrosoamines and the corresponding N-nitroamines. 2. The energy of the nitrogen-nitrogen bond in N-nitrosoamines may vary in the range 40–55 kcal, depending on the electronegativity of the substituent at the amino nitrogen atom.

1. Nitroalkylamines of variable structure were nitrosated by nitrous acid and its chloro- and fluoro-derivatives. On the example of 1,1,1,6,6,6-hexanitro-3-azapentane it was shown that weakly basic amines do not react with ClNO in nonpolar organic solvents. 2. The obtained nitroalkyl-N-nitrosamines are smoothly converted to N-nitramines by treatment with cone, nitric acid, but are not oxidized by trifluoroperacetic acid.

Tetranitro-fluoralkane, die nicht mehr als 2 Nitrogruppen an einem Kohlenstoff-Atom enthalten (I), lassen sich in Schwefelsaure mit Natriumnitrit oder mit Nitrosylchlorid bzw. -fluorid in Dichlorathan zu Polynitroalkyl-N-nitrosaminen (II) nitrosieren.

3-Fluoro-3, 3-dinitro-1-aminopropane condenses with CH2O and 1,1-dinitroalkanes to form Mannich bases which are readily converted to the corresponding N-nitro- and N-nitroso derivatives.
