Conclusions
-
1.
It was found that the final product of dissolution of metallic copper in a tetrahydrofuran solution of o-quinone in an excess of LiCl is a copper(II) biscatecholate complex.
-
2.
A scale of the electrode potentials characterizing the individual redox stages in the process of dissolution of copper in the conditions studied was elaborated; the scale permits predicting the capacity of copper and its cations and Q,\(SQ^{\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle-}$}}{ \bullet } }\) and Cat2− for mutual redox transformations in tetrahydrofuran.
