Nucleophilicity of Heteroaromatic TV-Oxides in Coordination with Zn(II) Tetraphenylporphyrinate and in the Substitution Reactions

摘要

Linear correlations have been revealed between thermodynamic and kinetic parameters of the nucleophilic substitution and coordination reactions of zinc(II) tetraphenylporphyrinate with heteroaromatic N-oxides in different solvents. Complex formation of zinc(II) tetraphenylporphyrinate with n-donor ligands in chloroform can serve as model system in spectroscopy studies of nucleophilicity and basicity of the compounds capable of the n,v type complexes formation.
