4. Acidity and organometallic anion formation

In the case of carbonyl iron, the carbonylate anion is generated without passing through the acid. This is an intramolecular redox reaction observed when carbonyl iron is placed in an alkaline medium: $[Fe {(CO)}_{5}] + 4 {OH}^{-} \to {[Fe {(CO)}_{4}]}^{2 -} + {CO}_{3}^{2 -} + 2 H_{2} O$
