Efficient and Selective Hydrosilylation of Carbonyl Compounds Catalyzed by Iron Acetate and N‐Hydroxyethylimidazolium Salts

“…In addition to the abovementioned substrates, we examined the reduction of 3'-nitroacetophenone, and found that this particular ketone reacted poorly giving only 20% yield of the corresponding alcohol after 24 h. Nitroacetophenones are known to be problematic in iron-catalyzed hydrosilylations as shown, for instance, by Royo and co-workers. [16] Overall, with the exception of 3'-nitroacetophenone, the catalytic system performed well for all examined substrates and the alcohols were obtained in good to excellent yields within a rather short reaction time (0.5 to 3 h) using a catalytic loading of 1 mol% iron acetate.…”

“…[15] In addition, Royo and coworkers demonstrated that similar iron complexes containing a tethered N-heterocyclic carbene (NHC) ligand catalyzed the reduction of aldehydes under hydrosilylation conditions. [16] The latter two studies demonstrate that N-heterocyclic carbenes, which are frequently used as ligands in various catalytic applications, [17] also are effective in iron-catalyzed hydrosilylations.…”

Synthesis, reactivity, and some photochemistry of ortho-N,N-dimethylaminomethyl substituted aryl and ferrocenyl pentamethylcyclopentadienyl dicarbonyl iron complexes

“…[25][26][27][28][29][30]. [33,34] despite the presence of the sterically demanding N-heterocyclic carbene-functionalized cyclopentadienyl ligand, while…”

Iron Nanoparticles Supported on Chemically‐Derived Graphene: Catalytic Hydrogenation with Magnetic Catalyst Separation

“…[1][2][3][4][5] In order to render catalytic hydrogenation reactions more efficient, many efforts have been made to decrease the costs for these reactions either by obtaining highly active catalytic species or by substituting inexpensive metals such as iron for the commonly used noble metals Pd and Pt. [6][7][8][9][10] The broad availability of iron makes it a desirable metal for catalysis. Furthermore, iron compounds are usually easy to handle and toxicologically inert.…”
