Abstract: An important task of modern organic chemistry is the discovery of new substances previously unknown to science, which could expand the area of our knowledge and replenish the range of high-energy or biologically active products. 3,7,10-Trioxo-2,4,6,8,9,11- hexaaza[3.3.3]propellane and its nitro derivatives are the newest products of the class of heterocycles; interest in this work. The chemistry of 3,7,10-trioxo-2,4,6,8,9,11-hexaaza[3.3.3]propellane is poorly understood and is represented by only two alkyl derivatives and theoretical calculations of the energy characteristics of nitro derivatives. The article presents the results of a study of the nitration of 3,7,10-trioxo-2,4,6,8,9,11-hexaaza[3.3.3]propellane (THAP) with concentrated nitric acid. It was found that in the process of nitration, there are two competing reactions - lactam-lactam rearrangement and nitration. It was shown that the reaction products strongly depend on the temperature of the reaction mixture. It was found that at a temperature of -40 ºС the formation of the lactimic form of THAP proceeds, whereas with a gradual increase in temperature, a mononitro derivative of propellane is first formed, and at a temperature of 40 ºС, the selective formation of 3,7,10-trioxo-2,6-dinitro-2,4,6,8,9,11-hexaaza[3.3.3]propellane in 30% yield.
