"The given dinitrodiamine I found during the nitration of 2-methylimidazole became immediately an object of attention of theoretical and synthetic chemists. At present time there are two feasible ways of synthesis. The first one is based on the nitration of 2-methylimidazolidine-4,5-dione (II), the second one on the nitration of 2-methylpyrimidine-4,6-diol (III). The synthesis based on diol III yields FOX-7 up to 95% but the disadvantage of this method is a formation of poisonous and explosive dinitromethane as a by-product. For this reason chemists focuse all efforts on the optimization of the first synthesis. In this paper both above mentioned strategic approaches will be evaluated, as well as attempts at alternative synteses (even though they resulted in failure in most cases). We will also discuss posibilities of transforming dinitromethane in the depleated nitration mixture into ecologicaly harmless products."@en . "RIV/60461373:22310/07:00018054!RIV08-MPO-22310___" . .
