Abstract

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.
