Double template effect in [4+4] Schiff base macrocycle formation: an ESI-MS study
journal contribution
posted on 2014-07-23, 12:17 authored by Julia Barreira-Fontecha, Rafal Kulmaczewski, Xiaomei Ma, Vickie McKeeThe mechanism of self-assembly of a polynuclear complex
of a [4 + 4] Schiff base iminomethylenediphenolate macrocycle
[BaCu4(4 + 4)]2+ via a non-macrocyclic dialdehyde intermediate
has been followed using ESI-MS of the reaction
solutions. Both assembly of the intermediate and Schiffbase
condensation with diamine give rise to single products;
formation of the intermediate metallacycle is fast but Schiffbase
condensation ismuch slower. Both intermediate complex
andmacrocyclic product have been structurally characterised.
