Conclusions
-
1.
The mechanism of the electrochemical reduction of hydrazones of isomeric nitrobenzaldehydes in dimethylformamide solution and possible chemical reactions accompanying the transfer of an electron to a molecule were considered.
-
2.
The formation of primary and secondary unstable anion radicals was established, their structure was determined, and the delocalization of the unshared electron in them was studied.
-
3.
A quantum chemical calculation was made of the distribution of spin density in the anion radicals studied. A comparison of the data obtained with the experiment permits a rather accurate description of the hyperfine splitting from the nitrogen atom in the hydrazone group.
