Redox characteristics of some activated olefinic double bonds as in malonitriles in nonaqueous acetonitrile at gold, platinum and glassy carbon electrodes have been extensively studied. They are oxidized in a single irreversible one‐electron process followed by deprotonation to form the dimer. On the other hand, the reduction occurs in two‐electron process to give the corresponding dianion which abstracts protons to saturate the bond. The effect of substituents present on the phenyl ring on the E 1/2 values has also been studied.
