Abstract

The methodology of 1H NMR study of the kinetics of the Ni(II) and Zn(II) cations complex formation with 2-aza-5,10,15,20-tetraphenyl-21-carbaporphyrin ([2-N, 21-CH]TPP I) was developed. The processes rate constants are determined using the pseudo-first and pseudo-second order models. It was shown that this methodology allows for identification and evaluation with high accuracy of the effects of donor–acceptor and solvation interactions that occur in the processes of the d-metal cations complex formation with the inverted tetrapyrrole macrocyclic ligands.
