STUDY ON RING CLEAVAGE AND ADDUCTIVE PROPERTY OF 2-(DINITROMETHYLENE)-4,5-IMIDAZOLIDINEDIONE

摘要

Ring cleavage of 2-(dinitromethylene)-4,5-imidazolidinedione (1) was achieved by methanol for the first time and the product was 1,1-diamino-2,2-dinitroethylene (FOX-7). 2, the first adduct of 1, was synthesized by the reaction of 1 with methanol in certain conditions and its structure was characterized. Physical and chemical properties of the adduct were studied. Parabanic acid was synthesized by decomposition of 1 in methanol, losing nitrogen oxides and carbon oxides.
