Kinetics of the Dissociation of Cu2+ and Co2+ Complexes of Nitro Derivatives of 5,15-Diphenyl-3,7,13,17-tetramethyl-2,8,12,18-tetraethylporphyrin in Proton-Donor Media

Resumo

Copper and cobalt complexes of nitro derivatives of planar and nonplanar derivatives of 5,15-diphenyl- 3,7,13,17-tetramethyl-2,8,12,18-tetraethylporphyrin are synthesized and their stability in proton-donor media is investigated. It is established that the kinetic parameters of the dissociation reactions of copper and cobalt complexes of the studied porphyrins depends on the degree of deformation of the porphyrin macroring and the acceptor properties of NO₂ groups.
