Table 5 The thermal decomposition of carbon – bonded anionic sigma complexes (1 – 3)

From: Synthesis of a new class of carbon–bonded anionic sigma complexes with 1,3-dimethyl-2,6-dioxo-5-(2,4,6-trinitrophenyl)-1,2,3,6-tetrahydropyrimidin-4-olate moiety as insensitive high energy density materials –– implications from impact sensitivity and thermal testings
