Conclusions
-
1.
It is shown that a number of aryl and acylhydrazones can be electrochemically carboxylated in non-aqueous media (acetonitrile, DMF) to give α-hydrazino (or hydrazido) acids.
-
2.
On passing from benzoyl to acetylhydrazones electrocarboxylation no longer occurs, probably because of the predominance in the acetylhydrazones of the EE′E″ form, in which the basicity of the imino nitrogen atom is lower than in the EE′Z″ form.
