Thermally Stable Rare-Earth Metal Complexes Supported by Chelating Silylene Ligands

The use of N-heterocyclic silylenes (NHSi) as ligands is a rapidly developing field. However, only a handful of f-element silylene complexes have been disclosed so far. Herein, we report the synthesis and characterization of a series of thermally stable d

Anchoring of silyl donors on a N-heterocyclic carbene through the cobalt-mediated silylation of benzylic C-H bonds

Pep up your carbene catalyst: A sequential cobalt-mediated C-H activation and silylation protocol has been developed for the preparation of novel silyl-donor-functionalized NHC complexes (see scheme; Mes=mesityl; R=H, Me, Ph). The resulting cobalt complexes exhibited high activity and selectivity as catalysts for the hydrosilylation of olefins. Copyright

Metal-free photocatalytic hydrosilylation of olefins in the presence of photoinitiators

A convenient metal-free photocatalytic hydrosilylation of a variety of linear and cyclic alkenes has been investigated. It was found that the free radical type photoinitiator Irgacure 2959 had a better effect on the hydrosilylation reaction; using 3 mol%

Nickel-Catalyzed Hydrosilylation of Terminal Alkenes with Primary Silanes via Electrophilic Silicon-Hydrogen Bond Activation

We report a simple and effective nickel-based catalytic system, NiCl2·6H2O/tBuOK, for the electrophilically activated hydrosilylation of terminal alkenes with primary silanes. This protocol provides excellent performance under mild reaction conditions: ex

Highly active cobalt complex catalysts used for alkene hydrosilylation

A series of nitrogen phosphine ligands were synthesized, and the hydrosilylation reaction of alkenes catalyzed using MCl2 in the presence of these ligands was investigated. FeCl2/1(N1, N1, N2, N2-Tetrakis[(diphenylphosphino)methyl]ethane-1,2-diamine) showed low catalytic activity. MnCl2/1, CrCl3/1 and NiCl2/1 showed some catalytic activity. The CoCl2/N,P-ligand catalyst system showed high activity as well as excellent selectivity (The selectivity of the β-adduct was ~100%.) in the hydrosilylation reaction. CoCl2/1 showed the highest catalytic activity (~ >99.9% conversion of 1-octene). Additionally, no α-adduct, dehydrogenative silylation product and octane were detected.

Efficient and selective alkene hydrosilation promoted by weak, double Si-H activation at an iron center

Cationic iron complexes [Cp?(iPr2MeP)FeH2SiHR]+, generated and characterized in solution, are very efficient catalysts for the hydrosilation of terminal alkenes and internal alkynes by primary silanes at low catalyst loading (0.1 mol%) and ambient tempera

Regioselective hydrosilylation of olefins catalyzed by co-iminobipyridine complexes: The role of cyclohexyl substituent on the imino nitrogen

Regioselective hydrosilylation of aliphatic olefins catalyzed by Co-iminobipyridine complexes, CoRa, were investigated, where R indicates a substituent on the imino nitrogen in an iminobipyridine ligand (iminobypyridine = [2,2¤-bpy]-6-C(Me)=N-R). Synthese

Cobalt(II) and (I) Complexes of Diphosphine-Ketone Ligands: Catalytic Activity in Hydrosilylation Reactions

The hydrosilylation of unsaturated compounds homogeneously catalyzed by cobalt complexes has gained considerable attention in the last years, aiming at substituting precious metal-based catalysts. In this study, the catalytic activity of well-characterized CoII and CoI complexes of the pToldpbp ligand is demonstrated in the hydrosilylation of 1-octene with phenylsilane. The CoI complex is the better precatalyst for the mentioned reaction under mild conditions, at 1 mol-% catalyst, 1 h, room temperature, and without solvent, yielding 84 % of octylphenylsilane. Investigation of the substrate scope shows lower performance of the catalyst in styrene hydrosilylation, but excellent results with allylbenzene (84 %) and acetophenone (> 99 %). This catalytic study contributes to the field of cobalt-catalyzed hydrosilylation reactions and shows the first example of catalysis employing the dpbp ligand in combination with a base metal.

Bench-Stable Cobalt Pre-Catalysts for Mild Hydrosilative Reduction of Tertiary Amides to Amines and Beyond

The readily synthesized and bench-stable cobalt dichloride complex (dpephos)CoCl2 is employed as a pre-catalyst for a diversity of silane additions to unsaturated organic molecules, including the normally challenging reduction of amides to amines. With regard to hydrosilative reduction of amides even more effective and activator free catalytic systems can be generated from the bench-stable, commercially available Co(acac)2 and Co(OAc)2 with dpephos and PPh3 ligands. These systems operate under mild conditions (100 °C), with many examples of room temperature transformations, presenting a first example of mild cobalt-catalyzed hydrosilylation of amides.
