Metal-directed ring-expansion in Schiff-base polypyrrolic macrocycles.
The reaction between a [2+2] Schiff-base porphyrin analogue and zinc acetate results in the unusual formation of an enlarged [3+3] macrocycle that is stabilised by metal coordination and intramolecular hydrogen-bonding interactions.
