Kinetics of the metal-ligand exchange of cadmium rhodo- and pyrroporphyrins with cobalt and zinc chlorides in organic solvents
摘要:
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.
