Abstract: The synthesis and characterization of a series of tetraarylporphyrins which bear covalently attached alkyl and aryl mercaptans designed to serve as axial ligands are described. The coordination chemistry of the iron (I1) complexes of these “mercaptan-tail” porphyrins has been investigated by IH NMR, IR, and electronic absorption spectroscopy, magnetic circular dichroism, and magnetic susceptibility measurements. Ferrous ...
