Abstract

The mechanism of self-assembly of a polynuclear complex of a [4 + 4] Schiff baseiminomethylenediphenolate 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 Schiff-base condensation with diamine give rise to single products; formation of the intermediate metallacycle is fast but Schiff-base condensation is much slower. Both intermediate complex and macrocyclic product have been structurally characterised.
