Popis:	The kinetics of the complex formation reaction of the β-hexamethyldiethylcorrole, [H3(β-Me6Et2)Cor], with zinc and cobalt acetates and with zinc acetylacetonate in DMF was studied. The rate of the complexation process between H3(β-Me6Et2)Cor and Zn(OAc)2 was shown to decrease in the following series of the solvents as DMF < AN < benzene and to suggest elevated chemical activity of the NH bonds in a molecule of corrole. The destruction of β-octaalkylcorrole in the basic solvents (DMF and DMSO) was discovered for the first time, and the kinetic parameters of this process were determined. With account for the structural distinctions between corroles H3Cor and porphyrins H2P, the probable mechanism of their reactions with metal salts was discussed and the transition state structure, which noticeably differ from the analogous reactions with porphyrins in the formation of the [H3Cor · Zn(OAc)2(Solv)n−3] intermediate.
