  • Intramolecularly donor-stabilized silenes: Part 6. The synthesis of 1-[2,6-bis(dimethylaminomethyl)phenyl]silenes and their reaction with aromatic aldehydes
    作者:Ute Bäumer、Helmut Reinke、Hartmut Oehme
    DOI:10.1016/j.jorganchem.2005.02.049
    日期:2006.1
    The intramolecularly donor-stabilized silenes (ArRSi)-Si-1=C(SiMe3)(2) (3a-d) (3a: R-1 = Me; 3b: R-1 = t-Bu; 3c: R-1 = Ph; 3d: R-1 = SiMe3; Ar = 2,6-(Me2NCH2)(2)C6H3) were prepared by treatment of the (dichloromethyl)oligosilanes (Me3Si)(2)R-1 Si-CHCl2 (la-l), with 2,6-bis(dimethylaminomethyl)phenyllithium (molar ratio 1:2). For 3c and 3d, X-ray structural analyses were performed indicating that only one dimethylamino group of the tridentate ligand is coordinated to the electrophilic silene silicon atoms, i.e., the central silicon atoms are tetracoordinated. The N -> Si donation leads to pyramidalization at the silene silicon atoms; the configuration at the silene carbon atoms is planar. For a chemical characterization 3a and 3c were treated with water to give the silanols (ArRSi)-Si-1(OH)-CH(SiMe3)(2) (5a,c). Studies of the reactions of 3a and 3c with benzaldehyde, 4-chlorobenzaldehyde or 4-methoxybenzaldehyde, respectively, revealed an unexpected reaction path leading to the substituted 2-oxa-1-sila-1,2,3,4-tetrahydronaphthalenes 12a, 12c, 13 and 14. Both 12a and 12c were structurally characterized by X-ray analyses. The formation of these six-membered cyclic compounds, which is discussed in detail, gives support to a dipolar mechanism for the general reaction of silenes with carbonyl derivatives.

  • 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
    作者:Piotr Pawluc、Grzegorz Hreczycho、Bogdan Marciniec
    DOI:10.1021/jo0616254
    日期:2006.10.1
    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)ethenes, which are then efficiently coupled in the presence of silver nitrate and palladium acetate with aryl or alkenyl idodides to give the corresponding 1,1-bis(silyl)-2-arylethenes
