Polarographic and Cyclic Voltametric Reduction of p-Chlorobenzaldehyde Isonicotinoylhydrazone

Article abstract of DOI:10.1246/bcsj.61.1397

p-Chlorobenzaldehyde isonicotinoylhydrazone (p-Cl-BAINH) exhibits a single wave in acid buffered solutions (pH 2-6) and two waves in alkaline buffered solutions (pH 7- 9).However, the compound exhibits three cathodic peaks in acid solution and two cathodic peaks in alkaline solutions.The electrode reactions are attributed to the reductive cleavage of =N-N- linkage and the reduction of the amide formed in the cleavage.
