H2Fe(CO)4 + KOH → K[HFe(CO)4] + H2O

Potassium tetracarbonyliron hydride is prepared by treating iron pentacarbonyl with potassium hydroxide:[3]

Fe(CO)5 + 2 KOH → K[HFe(CO)4] + KHCO3

Potassium tetracarbonyliron hydride is an intermediate in the synthesis of trisubstituted phosphine complexes:[4]

K[HFe(CO)4] + 3 PBu3 + EtOH → Fe(CO)2(PBu3)3 + EtOK + 2 CO + H2
