Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

The possibility of preparing isonicotinoylisopropylhydrazine by electrochemical reduction of the corresponding hydrazone on stationary solid electrodes (titanium, zirconium, nickel, iron, iron-based alloys) was demonstrated. The electrolysis is performed in the cathodic space of the electrolyzer on solid cathodes in aqueous-alcoholic solutions, with glassy carbon used as anode. The hydrazone electroreduction is performed at the cathodic current density of 0.1–0.5 A dm –2 in the temperature interval 40–70°С for 2–5 h. On electrodes with low overvoltage of hydrogen evolution, the C=N double bonds in isonicotinoylisopropylidenehydrazine relatively readily undergo electrohydrogenation with atomic hydrogen.
