Conclusions
-
1.
The absorption spectrum was recorded, and the value of the rate constant of the disproportionation of the o-benzosemiquinone radical QH. was obtained in the interaction with the Cu2+. It was shown that pKQH.>7.
-
2.
The formation of a complex between the radical QH. and the Cu2+ ions, with a 1∶1 composition, was demonstrated. The spectral kinetic characteristics of such a complex and the constant of complex formation were obtained.
