Compounds of amine-substituted cyclic amines: synthesis and structures

Neil F. Curtis Reactions of [M(en)2]2+ and [M(3,7-diaza-nonane-1,9-diamine)]2+, M = Cu2+, Ni2+, with nitroethane and formaldehyde in basic solution to form (nitro, methyl)-substituted cyclic tetraamine cations, and reduction of the nitro-group(s) to form (amine, methyl)-substituted cyclic tetraamine cations are reviewed. This Review covers the preparations and properties of compounds of amine‐substituted cyclic amines formed via nitroalkane‐aldehyde condensations of metal‐ion amine compounds, and such compounds with the amine substituents chemically modified.
