Abstract

The pyridine contracted to form the pyrrole ring. This transformation belongs to a unique class of reactions with the fundamental characteristic of the cleavage of the aromatic structure. By investigating the unusual coordination chemistry of N-confused pyriporphyrin with silver and gold ions, we observed this process and obtained several complexes that exhibited remarkable reactivity. This includes the reversible cleavage of C-O bonds and the selective demetallation of the outer metal ion.
