The indirect electrolytic oxidation of ketones (1) in methanolic sodium cyanide was studied using iodide ion as a mediator. The product and the reactivity of ketone were dependent on the nature of the alkyl groups attached to the carbonyl group. Thus, 2-alkyl and 2,2-dialkyl ketones afforded the corresponding oxiranecarbonitriles 2 along with small amounts of methyl oxiranecarboximidate 3, whereas acetophenones exclusively yielded benzoylpropanedinitriles 4.

An unprecedented reaction mode of cyanogenbromide has been discovered. Under basic conditions, cyanogenbromide acts as an equivalent of both Br+ and CN− to convert enolizable ketones into the corresponding cyanoepoxides in good yields. This unique reaction mode provides new, one‐pot access to densely substituted cyanoepoxides from easily available ketones (see scheme).
