Studien zur Reaktivität von Tris(benzylamino)guanidinium-Salzen mit Carbonylverbindungen und Isocyanaten

Abstract

This work should explore the reactivity and possible areas of application of triaminoguanidines. It has been shown that triaminoguanidines have a rich chemistry: 1. They can be functionalized in several ways, maintaining the C3-symmetry. The functionalization, achieved in this work, shows routes for the synthesis of novel dendrimers with a triaminoguanidinium core. 2. They represent a suitable platform for the design of extended three-dimensional molecular architectures and packages in the crystal. It could be shown that different triaminoguanidinium salts formed ionic layers in the crystal, whereby anions leading channels were observed. 3. They form goblet-shaped host-guest complexes, which are capable of complexing anions. 4. They serve as the starting compound for the synthesis of different, partly lesser-known nitrogen-rich heterocycles, like mesoionic 1,2,4-triazolium-5-amides.
