Electrochemical Transformations of Alkylidenemalonates into Substituted Cyclopropanecarboxylates.

Electrolysis of alkylidenemalonates in acetonitrile in the presence of sodium iodide as a mediator in an undivided cell leads to various substituted cyclopropanetetracarboxylates depending on the conditions of the electrolysis and on the structure of the starting alkylidenemalonate.
