    摘要:
    从TsiSiX(3)与萘锂的反应合成了在室温下稳定的卤化亚烯基(Tsi)X(2)SiLi(Tsi = C(SiMe(3))(3),X = Br,Cl)。溴化烯类化合物在-78摄氏度和室温下与tBuOH和MeI反应,分别以高收率分别得到(Tsi)HSiBr(2)和(Tsi)MeSiBr(2);这清楚地表明了它的亲核性。在溴化烯类化合物与甲醇,2-丙醇和2,3-二甲基-1,3-丁二烯的反应中,相应的产物(Tsi)HSi(OMe)(2),(Tsi)HSi(OiPr)Br和以高收率获得了溴(Tsi)silacyclopent-3-ene;这证明了其两亲性,好像会捕获溴亚甲硅烷基一样。绿皮烯类化合物还表现出亲核和两亲性质。(Tsi)Br(2)SiLi,(Tsi)Br(2)SiK和(Tsi)Cl(2)SiLi的(29)Si化学位移分别为106、70和87 ppm,

    Structure and dynamics of hindered organosilicon compounds. The conformations of symmetrical (Me3Si)3C and (PhMe2Si)3C derivatives
    摘要:
    At low temperatures the methyl region of the H-1 and C-13 NMR spectra of (Me3Si)3CSiCl3 and the H-1 NMR spectrum of (Me3Si)3CSiBr3 each show three signals of equal intensity and the Si-29 NMR spectrum of the trichloride shows only one Me3Si signal. These data are consistent with the methyls within each Me3Si group becoming inequivalent. Compounds containing the (PhMe2Si)3C group are able to adopt different conformations at low temperature; in (PhMe2Si)3CSiCl3 the phenyl groups mesh together while in (PhMe2Si)3CBr they are separated by methyl groups. These different arrangements of the ligand can readily be distinguished by H-1 NMR spectroscopy, and the conformation in the case of (PhMe2Si)3CSiCl3 has been confirmed in the solid state by X-ray crystallography.

    Sila-heterocycles, ditrisyldibromodisiladioxetane (trisyl = C(SiMe3)3) 2 and ditrisyldibromodithiadisiletane 3, were generated at a low temperature from the reaction of trisylbromosilylenoid 1 with heterocumulenes such as phenyl isocyanate and phenyl isothiocyanate. The 29Si-NMRs of sila-heterocycles were then investigated. The reaction of cyclic compounds 2 and 3 with MeOH gave dimethoxy(trisyl)silanol

    日期:2004.5
    Silylium ions stabilized by Si–X–Si three-center bonds (X = halogen or hydrogen) (2a–d) have been synthesized by the reaction of the corresponding 1-tris(trimethylsilyl)methyl-2,3-bis(trimethylsilyl)-1-silacyclopropene derivatives (1a–d) with triethylsilyl benzenium tetrakis(pentafluorophenyl)borate. Structural and theoretical studies of 2a–d showed Si–X–Si three-center bonding with halonium ion character for 2a–c, and 3c–2e Si–H–Si bonding for 2d.

    A highly thermally stable silylenoid, trisyl(aminomethylphenyl)silylenoid (2) was synthesized from the reaction of dimethylaminomethylphenyllithium with a bromosilylenoid, 1. Silylenoid 2 reacted with electrophiles to give the corresponding products, but did not react with alkyllithiums as a nucleophile. (C) 2011 Elsevier B. V. All rights reserved.
