โฆ Synopsis
In the absence of NaC1 the two waves observed in an alkaline medium are even less reSolved, and the total limiting current decreases steadily at potentials more negative than -1.3 V. ** See later coulometric results.

In DMF KC104 2.0 x 10-2 F the discharge begins at about -1.90 V. If the same solution contains also 2.0 ร 10 -4 F CH/C1COOH the discharge begins at about -1.75 V.
Electrochemical reduction ofcyclic and acyclic derivatives of 2,3-butanediol lo C,-hydrocarbons was examined. Among the derivatives, the cyclic sulphate was directly reduced to 2-butene; thediacatatc and dimethanesulphonatc also gave 2-butene but by indirect reduction with electrogenerated amalgam.
2, -one] is a widely used weed controlling agent. In aqueous solutions and in 30 % v/v acetonitrile/water solutions it is reduced in two two-electron steps. In both steps protonated forms of azomethine bonds are reduced, in the more positive the 1,6-bond, in the more negative (by about 0.4 V) the 2
The electroreduction behavior of tetraphenylcyclopentadienone (tetracyclone) and some of its m,m'-and p,p'-substituted derivatives in acetonitrile was investigated. The mechanism for the electroreduction of these compounds in the absence and in the presence. of protons was proposed using the results
