Conclusions
-
1.
A new method was proposed for obtaining the o-semiquinolate complexes of the transition metals, which consists of reacting the salts of the acids of the metals, or of their halides, with substituted pyrocatechols in the presence of a base and atmospheric oxygen.
-
2.
It was shown that oxidation-reduction transitions can take place between the pyrocatechol and o-semiquinolate complexes.
