Importance of co-donor field strength in the preparation of tetradentate α-diimine nickel hydrosilylation catalysts.
Although bis(α-diimine)Ni complexes were prepared when amine-substituted chelates were added to Ni(COD)2, the incorporation of strong-field phosphine donors allowed the isolation of (κ(4)-N,N,P,P-DI)Ni hydrosilylation catalysts. The crystallographic investigation of two different (κ(4)-N,N,P,P-DI)Ni compounds revealed that the geometry about nickel influences the observed degree of α-diimine re...
متن کاملSelective reduction of carboxylic acids to aldehydes through manganese catalysed hydrosilylation.
The direct reduction of carboxylic acids to disilylacetals was achieved through a manganese catalyzed hydrosilylation reaction in the presence of triethylsilane under mild conditions, at r.t. and under UV irradiation (350 nm). The aldehydes were obtained in good to excellent yields after acidic hydrolysis.
متن کاملRuthenium catalyzed selective hydrosilylation of aldehydes.
A chemoselective hydrosilylation method for aldehydes is developed using a ruthenium catalyst [(Ru(p-cymene)Cl2)2] and triethylsilane; a mono hydride bridged dinuclear complex [{(η(6)-p-cymene)RuCl}2(μ-H-μ-Cl)] and a Ru(iv) mononuclear dihydride complex [(η(6)-p-cymene)Ru(H)2(SiEt3)2] are identified as potential intermediates in the reaction and the proposed catalytic cycle involves a 1,3-hydri...
متن کاملHomogeneous gold-catalyzed hydrosilylation of aldehydes
The catalytic hydrosilylation of aldehydes in the presence of PBu3 modified Au(I)-complexes was investigated. In situ IR and NMR experiments have revealed that both, the ligand PBu3 and the substrate aldehyde play an important role in stabilizing the gold catalyst and/or forming the catalytically active species. In their absence the reducing power of silane destabilizes the gold (I) catalyst gi...
متن کامل[MoO2Cl2] as catalyst for hydrosilylation of aldehydes and ketones.
The high valent molybdenum-dioxo complex [MoO2Cl2] catalyzes the addition of dimethylphenylsilane to aldehydes and ketones to afford the corresponding dimethylphenylsilyl ethers in quantitative yield.
