In combination with different aromatic N,N ‐donors, iron acetate and octanoate are suitable catalyst precursors for the hydrosilylation of carbonyl compounds. Iron octanoate can be used to perform this catalytic transformation in cheap and non‐toxic petrol ether or heptane as the solvent and with versatile polymethylhydrosiloxane (PMHS) as the silane source. Investigation of the preformed catalyst (iron octanoate+ N,N ‐ligand+PMHS) by using Mössbauer spectroscopy suggests that the active species is a high‐spin iron(II) system.
