Iron piano-stool phosphine complexes for catalytic hydrosilylation reaction

A family of six cyclopentadienyl–iron carbonyl complexes bearing phosphine ligands (PPh3, PMe2Ph and PCy3) with iodide or PF6 as a counter-anion were prepared and used as catalysts for the hydrosilylation of carbonyl derivatives. Aldehydes were reduced at 30 °C, using PMHS as the silane, whereas ketones were reduced at 70 °C using PhSiH3.
