Macrocyclic ligands synthesis

Generation of free macrocycles from their metal complexes The removal of a macrocycle from its coordinated metal ion is a frequent procedure in macrocyclic ligand synthesis - conditions for inducing such demetallations are now briefly discussed ...

In some of the earliest experiments involving in situ macrocyclic ligand synthesis, it was shown that the reaction of 2,6-diacetylpyridine with certain polyamines in the presence of metal ions leads to the preparation of new macrocyclic complexes. As is often the case with Schiff-base condensations of the type, the addition of a small amount of acid catalyzes the reaction. Thus treatment of 2,6-diacetylpyridine with 3,3 -diaminodipropylamine [A-(3-aminopropyl)-l,3-pro-panediamine] in the presence of nickel(II) leads to the isolation of nickel complexes of the macrocyclic ligand (Me2-Pyo[14] trieneN4).
