| Abstract: | Zinc(II) and ruthenium(II) monohydroxyporphyrinates with a different arrangement of the reaction center in the meso-aryl moiety of the macrocycle were synthesized, and their ability of complexing with the methyl esters of glycine and m-aminobenzoic acid in toluene were studied using the methods of spectrophotometric titration and 1H NMR spectroscopy. The stability constants of the resulting complexes and concentration ranges of their existence were determined. |
