TLDR
The electrochemical study of β-chlorovinylaldehydes was carried out in DMF in the presence of 0·1 M NBu4ClO4 as the supporting electrolyte as mentioned in this paper.Abstract:
The electrochemical study of β-chlorovinylaldehydes, namely, 4-chloro-3-formyl-2H (1)-benzopyran and β-chlorocinnamaldehyde was carried out in DMF in the presence of 0·1 M NBu4ClO4 as the supporting electrolyte. Both the depolarizers give three diffusionlimited polarographic waves and the corresponding cathodic peaks in cyclic voltammetry. Their microcoulometric data indicate a transfer of four-electrons (n app=4) in the electrode process. The macroscale controlled-potential electrolysis of the depolarizers afforded only blackish-brown tarry product. A mechanism is suggested for their reduction in DMF under polarographic conditions.read more

TL;DR: In this paper, the same authors showed that the mechanism of reduction at a hanging mercury drop electrode with a constant surface differs from that at a dropping mercury electrode (DME) in terms of the potential region where propionaldehyde is reduced.

TL;DR: In this article, the rate of protonation of the radical anion formed in the uptake of the first electron decreases with increasing pH, the two-electron reduction wave of cinnamaldehyde decreases to a oneelectron wave.
