Recently synthesized a new energetic material 2,2-dinitroethene-1,1-diamine (FOX-7) has significant potential for application due to its high performance and very low sensitivity. Generally, explosion is based on thermally initiated chain of intramolecular redox reactions. It has been found that electrochemical reduction of FOX-7 in aqueous as well as in non-aqueous solutions is also able to provoke the chain of follow-up processes leading to total decomposition of the parent substance. As intermediates radical species were proved in aprotic media. Moreover, instead of organic amines, namely gaseous products were identified after exhaustive electrochemical reduction. For these investigations various electrochemical methods both in analytical, as well as in preparative scale were utilized, together with UV-Vis spectroscopy. The detailed understanding of the mechanism and analysis of individual reaction steps is under further study.
