Mono complexes diamine synthesis

The following two synthetic techniques are applied for obtaining complexes of aliphatic, aromatic, and heterocyclic imines in the limits of the discussed variant of the template synthesis interaction of coordinated mono- and diamines with mono- and dicarbonyl derivatives (method A) and reactions of complexes of o-hydroxyalde-hydes (ketones) with amines and diamines (method B). The simplest transformation of this type is represented by the reaction (3.176) [53,54] ... 

Divergent synthesis of POPAM dendrimers is based on the concept developed by Vogtle et al. in 1978 (see Section 1.1) [4]. Acrylonitrile is added to a primary mono- or oligo-diamine in a Michael reaction (Fig. 4.2). Suitable reducing agents are Co(II)-borohydride complexes or diisobutylaluminium hydride [5]. Subsequent iterative reaction cycles permit repeated addition of acrylonitrile followed by reduction until the limiting generation is reached.
