CpFe(CO)2 anion-catalyzed highly efficient hydrosilylation of ketones and aldehydes

K[CpFe(CO) 2 ] and [NEt 4 ][CpFe(CO) 2 ] enabled highly efficient hydrosilylation of ketones and aldehydes with PhSiH 3 to synthesize tris- and bis(alkoxy)silanes in excellent yields depending on the substituents on the carbonyl compounds.
