Oxidation of the ethane-bridged dimer of coproporphyrin-I proceeds stereoselectively to produce only the sterically unhindered trans-ethylene-bridged atropisomer, which undergoes thermal isomerisation to give two atropisomers of the cis-dimer.

a monocarbonyl complex of ruthenium(II) porphyrin that exists as a coordination polymer formed owing to intermolecular axial bonding between the oxygen atoms of carboethoxyl groups and ruthenium(II). The structure proposed for second product (3) is in the form of the corresponding monomer of a monocarbonyl complex of ruthenium(II) porphyrin. It is established that polymeric complex 2 transforms into
