Regio- and stereoselective approach to 1,2-di- and 1,1,2-trisilylethenes by cobalt-mediated reaction of silyl-substituted dibromomethanes with silylmethylmagnesium reagents

(Chemical Equation Presented) Functional ethenes: Treatment of dibromo(silyl)methanes 2 a with silylmethyl Grignard reagents 1 and catalytic CoCl2 affords (E)-1,2-disilylethenes 3 a in excellent yields. Dibromodisilylmethanes 2 b undergo a simi

Insertion of Vinylsilane into the Ruthenium-Silicon-Bond - Direct Evidence for the Non-metallacarbene Mechanism of Silylalkene Disproportionation

The reversible insertion of the vinylsilane molecule into the Ru-Si bond occurs in two different ways to give E-1,2-bis(silyl)ethene and 1,1-bis(silyl)ethene which, in combination with the previous experiments by Wakatsuki et al., provides convincing evidence for a non-metallacarbene mechanism of silylalkene disproportionation.

Synthesis and application of a new selenoplatinum catalyst

The reaction of 4-methyl-5-ethoxycarbonyl-1,2,3-selenadiazole with (PPh3)4Pt leads to the formation of a new platinum-containing heterocyclic system. It was found that the selenoplatinum complex is a selective catalyst for the hydrosilylation of terminal alkynes to yield β-(Z)- and β-(E)-silylethylenes.

Highly selective hydrosilylation of olefins and acetylenes by platinum(0) complexes bearing bulky N-heterocyclic carbene ligands

Platinum complexes bearing bulky N-heterocyclic carbene (NHC) ligands, i.e., [Pt(IPr?)(dvtms)] (where, IPr? = 1,3-bis{2,6-bis(diphenylmethyl)-4-methylphenyl}imidazol-2-ylidene) and [Pt(IPr?OMe)(dvtms)] (where, IPr?OMe = 1,3-bis{2,6-bis(diphenylmethyl)-4-m

The cobalt(II) complex of a new tridentate Schiff-base ligand as a catalyst for hydrosilylation of olefins

Condensation of 1-methyl-2-imidazolecarboxaldehyde with 2-(1-methylhydrazinyl)pyridine results in the synthesis of new, tridentate Schiff-base ligand L, which readily reacts with CoCl2 to form a monometallic [CoLCl2] complex that, upon reduction, functions as active hydrosilylation catalyst. The ligand and the [CoLCl2] catalyst have been characterized spectroscopically (MS, NMR, FTIR) and by single crystal X-ray diffraction techniques. The results of preliminary catalytic experimentation show that the cobalt complex can induce hydrosilylation and dehydrogenative silylation of olefins, depending upon the hydrosilane substrate used.

Copper(II)-catalyzed highly regio- and stereoselective hydrosilylation of unactivated internal alkynes with silylborate in water

The highly regio- and stereoselective hydrosilylation of internal alkynes with silylborate catalyzed by Cu(OTf)2 with 1,10-phenanthroline as the ligand in the presence of Cs2CO3 in water is developed. This protocol was applied efficiently in the aqueous synthesis of multi-substituted vinylsilanes.

New organoplatinum (IV) complex with quaterpyridine ligand: Synthesis, structure and its catalytic activity in the hydrosilylation of styrene and terminal alkynes

The reaction of ligand L with PtCl2 leads to a novel structural motif of octahedral ortho-metalated complex of formula [Pt(L-H) Cl3] 1. This result is a consequence of drastic conditions of reaction and preferred Pt(IV) octahedral coordination geometry. The new compound has been characterised on the basis of the spectroscopic data in solution, and its structure confirmed in the solid state by X-ray crystallography (1a - [Pt(L-H)Cl3]·MeOH, 1b - [Pt(L-H)Cl 3]·C6H5CH3). This article reports organoplatinum (IV) complex 1 as effective and highly selective catalyst precursor in the hydrosilylation of styrene and terminal alkynes.

Selective hydrosilylation of 1-alkynes using iridium catalyst with biphosphinine ligand

The iridium-catalyzed hydrosilylation of alkynes in the presence of 4,4′,5,5′-tetramethylbiphosphinine (tmbp) has been explored. The hydrosilylation of alkynes in the presence of tmbp proceeds effectively to give β-(E)-vinylsilanes highly selectively in m

Chemoselective silylzincation of functionalized terminal alkynes using dianion-type zincate (SiBNOL-Zn-ate): Regiocontrolled synthesis of vinylsilanes

A regio- and chemoselective silylzincation reaction of various functionalized alkynes was developed using a newly designed dianion-type zincate. Silylzincation of terminal alkynes, followed by electrophilic trapping, proved to be a powerful tool for the one-pot, regiocontrolled generation of trisubstituted functionalized alkenes. The functionalized vinylzincate intermediate also undergoes copper- and palladium-catalyzed C-C bond-forming reactions in high yields and with high regio- and chemoselectivities. Copyright

Catalysis of hydrosilylation: Part XXXIV. High catalytic efficiency of the nickel equivalent of Karstedt catalyst [{Ni(η-CH2=CHSiMe2)2O} 2{μ-(η-CH2=CHSiMe2)2O}]

The nickel equivalent of Karstedt catalyst [{Ni(η-CH2=CHSiMe2)2O} 2{μ-(η-CH2=CHSiMe2)2O}] (1) appeared to be a very efficient catalyst for dehydrogenative coupling of vinyl derivatives (styrene, vinylsilanes, vinylsiloxanes) with trisubstituted silanes HSi(OEt)3, HSiMe2Ph. The reaction occurs via three pathways of dehydrogenative coupling, involving formation of an unsaturated compound as the main product as well as a hydrogenated olefin (DS-1) pathway, hydrogenated dimeric olefin (DS-2) and dihydrogen (DC), respectively. The reaction is accompanied by side hydrosilylation. Stoichiometric reactions of 1 with styrene and triethoxysilane, in particular synthesis of the bis(triethoxysilyl) (divinyltetramethyldisiloxane) nickel complex 3 and the first documented insertion of olefin (styrene) into Ni-Si bond of complex 3, as well as all catalytic data have allowed us to propose a scheme of catalysis of this complex reaction by 1.
