Template Synthesis of Macrobicyclic Large Cavities of the Tris-(bipyridine)-TypeThe synthesis of the ligands 2 and 3 has been performed in a one-step procedure starting with the triamines 11 and 12 and 5,5′-bis(bromomethyl)-2,2′-bipyridine (6). The new macrobicyclic compounds were isolated and characterized as their sodium complexes. Dynamic 1H-NMR investigations reveal the conformational flexibility of the complex 2 · Na⊕.
Notes:
Die Liganden 2 und 3 wurden in einer Eintopf-Synthese ausgehend von den Triaminen 11 und 12 sowie 5,5′-Bis(brommethyl-2,2′-bipyridin (6) erhalten und als Natrium-Komplexe isoliert und charakterisiert. Die dynamische 1H-NMR-Spektroskopie des Komplexes 2 · Na⊕ belegt seine konformative Beweglichkeit.
