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

K[CpFe(CO)₂] and [NEt₄][CpFe(CO)₂] enabled highly efficient hydrosilylation of ketones and aldehydes with PhSiH₃ to synthesize tris- and bis(alkoxy)silanes in excellent yields depending on the substituents on the carbonyl compounds. The catalyst represents one of the most efficient and practical iron catalysts for hydrosilylation of carbonyl compounds with a TOF up to 24 540 h⁻¹. [ABSTRACT FROM AUTHOR]
