The carbanions of malononitrile, ethylmalononitrile, and dimethyl malonate react with pentacyanonitrosylferrate (nitroprusside) to form highly coloured adducts. A kinetic study has shown that, in the second and third cases, there is rate-determining reaction between carbanion and nitroprusside but, in the first, the product is that formed by a second ionisation to give [Fe(CN)5N(O)C(CN)2]4-.
