Protonation constants of several α-mercapto-β-aryl acrylic acids and constants for formation of complexes between these ligands and bivalent metal cations were determined by computer-assisted analysis of p H-titration data. Ligand-metal ion mixtures in 50%(v/v) dioxane-water and in water, I= 0.1 M (NaClO4) were titrated at 25° C with sodium hydroxide. Initial estimates of complex formation constants were refined with the SCOGS program. ...
