3-azabicyclo[3.3.1]nonane derivatives: IX. Synthesis and molecular structure of 3-azabicyclo[3.3.1]nonane-1,5-diamines in solution and in solid state

During catalytic reduction with hydrogen on nickel of a series of 3-substituted 1,5-dinitro-3-azabicyclo-[3.3.1]non-6-enes alongside nitro groups reduction occurred also hydrogenation of the double bond. New diamines of the 3-azabicyclo[3.3.1]nonane series were synthesized, and their structure was established by means of IR, 1H and 13C NMR spectroscopy and X-ray diffraction study.
