Synthesis and transformations of polyhedral compounds

Derivatives of 1,3-diaza- and 1,3,5-triazaadamantanes react with 1,2-dibromoethane in the presence of base to give derivatives of 1,4-diaza- and 1,3,6-triazahomoadamantanes, respectively. Schiff bases were obtained containing the 1,3,6-triazahomoadamantane ring.
