Abstract


Linear correlations were found between the thermodynamic and kinetic parameters for the nucleophilic substitution and coordination of metalloporphyrins in various solvents with the participation of pyridines. Complex formation of zinc(II) tetraphenylporphyrin with n-donor ligands in chloroform at 25°C is proposed for use as a model system in the electronic spectroscopic investigation of the nucleophilicity and basicity of compounds capable of forming complexes of the n,ν type.
