A facile synthesis of 1,1-bis(silyl)ethenes

(Chemical Equation Presented). Symmetrical 1,1-bis(silyl)ethenes have been easily prepared via ruthenium complex-catalyzed silylative coupling cyclization of 1,2-bis(dimethylvinylsiloxy)ethane to give 2,2,4,4-tetramethyl-3-methylene-1, 5-dioxa-2,4-disilac

Construction of highly sterically hindered 1,1-disilylated terminal alkenes

One direct and efficient procedure for the synthesis of 1,1-disilylated terminal alkenes is demonstrated in this paper. To overcome and rationally utilize the steric hindrance of silyl units, the cationic ruthenium catalyst [CpRu(MeCN)3]+ was found to be effective for Markovnikov hydrosilylation of 1-silyl terminal alkynes with high yields and excellent regioselectivity. Dissimilarities between alkyl and alkoxy silyl units lead to versatile product derivatizations toward a variety of useful building blocks.

Phosphine-stabilized, oxide-supported rhodium catalysts for highly efficient silylative coupling reactions

Oxide-supported rhodium catalysts with excellent activity in silylative coupling reactions have been developed. Reductive pretreatment of the catalysts in the presence of 0.5 equiv triphenylphosphine under a hydrogen atmosphere enhanced and stabilized the

Efficient synthesis of E-1,2-bis(silyl)ethenes via ruthenium-catalyzed homocoupling of vinylsilanes carried out in ionic liquids

A series of ruthenium complexes (RuCl3 × 3H2O, [C5H5Ru(CH3CN)3]+[PF 6]-, [RuCl2(PPh3)3], [RuHCl(CO)(PPh3)3

Shuffle off the classic β-Si elimination by Ni-NHC cooperation: Implication for C-C forming reactions involving Ni-alkyl-β-silanes

Via a cooperation of NHC, Si substituents and a M center, β-Si elimination was attenuated, revealing a new way to attain a high Ni-β-SiR3:Ni-σ-SiR3 ratio. The scope is illustrated by a head-to-tail vinylsilane-α-olefin hydroalkenylation.

Synthesis and structural characterisation of alkali metal complexes of heteroatom-stabilised 1,4- and 1,6-dicarbanions

A straightforward Peterson olefination reaction between either [{(Me 2PhSi)3C}Li(THF)] or in situ-generated [(Me 3Si)2{Ph2P(BH3)}CLi(THF) n] and paraformaldehyde gives the alkenes (Me2PhSi) 2C=CH2 (1) and (Me3Si){Ph2P(BH 3)}C=CH2 (2), respectively, in good yield. Ultrasonic treatment of 1 with lithium in THF yields the lithium complex [{(Me 2PhSi)2C(CH2)}Li(THF)n]2 (3), which reacts in situ with one equivalent of KOBut in diethyl ether to give the potassium salt [{(Me2PhSi)2C(CH 2)}K(THF)]2 (4). Similarly, ultrasonic treatment of 2 with lithium in THF yields the lithium complex [[{Ph2P(BH 3)}(Me3Si)C(CH2)]Li(THF)3] 2.2THF (5). The bis(phosphine-borane) [(Me3Si){Me 2(H3B)P}CH(Me2Si)(CH2)]2 (6) may be prepared by the reaction of [Me2P(BH3) CH(SiMe3)]Li with half an equivalent of ClSiMe2CH 2CH2SiMe2Cl in refluxing THF. Metalation of 6 with two equivalents of MeLi in refluxing THF yields the lithium complex [[{Me2P(BH3)}(Me3Si)C{(SiMe2) (CH2)}]Li(THF)3]2 (9), whereas metalation with two equivalents of MeK in cold diethyl ether yields the potassium complex [[{Me2P(BH3)}(Me3Si)C{(SiMe2) (CH2)}]2K2(THF)4]∞ (10) after recrystallisation. X-Ray crystallography shows that, whereas the lithium complex 5 crystallises as a discrete molecular species, the potassium complexes 4 and 10 crystallise as sheet and chain polymers, respectively.

A new selective approach to 1,1-bis(silyl)-2-arylethenes and 1,1-bis(silyl)-1,3-butadienes via sequential silylative coupling-heck coupling reactions

A novel selective route to 1,1-bis(silyl)-1-alkenes has been developed. Sequential one-pot silylative coupling exo-cyclization of 1,2- bis(dimethylvinylsiloxy)ethane followed by the reaction with Grignard reagents leads to the desired 1,1-bis(silyl)ethene

Reactions of gem-dibromo compounds with trialkylmagnesate reagents to yield alkylated organomagnesium compounds

The reaction of gem-dibromocyclopropanes 5 with nBu3MgLi affords butylated cyclopropylmagnesium species that can be trapped with various electrophiles. The reaction of dibromomethylsilanes 12 requires the addition of a catalytic amount of CuCN · 2 LiCl for smooth migration of the alkyl groups. The resultant α-silylpentylmagnesium compounds 16 react with electrophiles, such as acyl chlorides or α, β-unsaturated ketones to afford α- or γ-silyl ketones, respectively. Treatment of dibromodisilylmethanes with Me3MgLi yields 1-bromo- 1,1-disilylethanes 25 that can be converted into 1,1-disilylethenes 29 by dehydrobromination.

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.
