Bu4N[Fe(CO)3(NO)]-Catalyzed Hydrosilylation of Aldehydes and Ketones

The nucleophilic Fe complex Bu4N[Fe(CO)3(NO)] (TBAFe) has been used as a highly active catalyst for the mild hydrosilylation of a variety of functionalized aldehydes and ketones using inexpensive PMHS as stoichiometric reductant. The corresponding alcohols were obtained in good‐to‐excellent yields a...

Zusammenfassung:	The nucleophilic Fe complex Bu4N[Fe(CO)3(NO)] (TBAFe) has been used as a highly active catalyst for the mild hydrosilylation of a variety of functionalized aldehydes and ketones using inexpensive PMHS as stoichiometric reductant. The corresponding alcohols were obtained in good‐to‐excellent yields at low catalyst loadings of only 1 mol‐% and reaction temperatures of 30–50 °C. A variety of ketones and aldehydes have been reduced in the presence of only 1 mol‐% of Bu4N[Fe(CO)3(NO)] (TBAFe) at low temperatures with inexpensive polymethylsilane (PMHS) as the hydride source.
