Procedure

Finely ground 2-methyl-4,5pyrimidindione (5.1 g, 0.05 mole) was dissolved in concentrated sulphuric acid (40 ml, 1.84 g/cm3) at 15-20° C. during vigorous stirring. At the same temperature nitric acid (8.0 ml, 1.52 g/cm3) was added over a 30-min period. After 3 h, the reaction mixture was poured into water. Within a few seconds, bright yellow crystals settled out (1,1-diamino-2,2-dinitroethylene). The precipitate were washed with water and dried at 50° C. 2.6 g 1,1-diamino-2,2-dinitroethylene was recovered (35% yield).
