Heating 1,5-dinitro-3,7-di(tert-butyl)-3,7-diazabicyclononane with concentrated hydrobromic acid gives 1,5-dinitro-3,7-diazabicyclononane.Cyclization of the latter with various aldehydes and ketones gave a series of 2,2-disubstituted 5,7-dinitro-1,3-diazaadamantanes.The behavior of the synthesized compounds under electron impact has been studied.
