The carbanion of ethyl cyanoacetate reacts with pentacyanonitrosylferrate (2–)(nitroprusside) to form a coloured adduct, which decomposes to an oxime and aquapentacyanoferrate (3–). Although the pKa of ethyl cyanoacetate is similar to that of malononitrile, no second ionisation could be detected in the kinetic data. Reasons for this are discussed.
