Azo bond hydrogenation with hydrazine, R–NHNH2, and hydrazobenzene
摘要:
Hydrogenation of azo bonds with hydrazine, mono-substituted hydrazine, and hydrazobenzene was studied with selected diazene compounds under oxygen-free conditions. The reactions proceed rapidly and in high yield in several solvents, utilizing all N-H protons. While the reduction process is accompanied by the evolution of nitrogen gas in the case of N(2)H(4), the intermediacy of diimide could not be confirmed by standard trapping experiments.

most of the salts exhibit excellent impact sensitivities (>40 J), friction sensitivities (>360 N), and are insensitive to electrostatics. The measured densities of these energeticsalts range from 1.64 to 2.01 g cm−3. The detonation pressure values calculated for these salts range from 14.6 to 29.2 GPa, and the detonation velocities range from 6536 to 8275 m s−1; these values make the salts potential
