Double metal-ligand exchange in solvate complex-metal porphyrin systems
摘要:
The kinetics and mechanism of one of the most complicated chemical reactions of coordination compounds, where two different porphyrin complexes exchange central metal ions and the corresponding ligands, were considered using a number of metal porphyrins as substrates.

Experimental data on electron absorption spectra (EASs) and the kinetics of substitution of Co2+ for the central Cd2+ ion in rhodoporphyrin complexes (CdRodP) in the reaction with CoCl2 in acetonitrile (AN) and ZnCl2 in dimethyl sulfoxide (DMSO) and the substitution of Zn2+ for Cd2+ in pyrroporphyrin complexes (CdPyrP) in the reaction with ZnCl2 in DMSO are reported and discussed. The evolution of EASs in the reaction of metal-ligand exchange and the effective and true rate constants of the exchange reaction are reported. The activation energies and activation entropies are estimated.
