Abstract

The thermodynamic stability of the antiaromatic 4,8-dihydrodifurazano[3,4-b,e]pyrazine (I) was studied by a quantum-chemical method. The molecular structure was investigated by X-ray crystallographic analysis, and the aromaticity index of the compound was calculated. It was shown that the oxidation or nitration of compound (I) leads to a stable aromatic radical.
