  • Chloroboration and allied reactions of unsaturated compounds
    作者:F. Joy、M.F. Lappert、B. Prokai

    日期:1966.6
    The reactions of boron halides (Cl, Br) and of some organoboron chlorides with olefins have been investigated. Detailed results are presented on cyclohexene, allene, 1,5-cyclooctadiene, norbornadiene, cyclooctatetraene, and cycloheptatriene. It is clear that boron trichloride reacts only with the most reactive of olefins (the last three), so that the first-formed product may react further and prevent
    研究了卤化硼(Cl,Br)和某些有机氯化硼与烯烃的反应。给出了有关环己烯,丙二烯,1,5-环辛二烯,降冰片二烯,环辛二烯和环庚三烯的详细结果。显然,三氯化硼仅与反应性最高的烯烃(最后三种)反应,因此第一种形成的产物可能会进一步反应并阻止可逆的脱氯硼化作用。相似的溴化硼酸酯似乎不那么容易,并且一般的反应模式是烯烃产生相应的烯基二溴硼烷,烷基二溴硼烷和烷基溴化物。

    A novel and general method for the hydroboration of alkenes, including aryl alkenes, 1,1-disubstituted alkenes, aliphatic alkenes, and bio-derived alkenes, using BX3 as the boration reagent in the presence of iPr2NEt is reported. The reaction was also applied to the synthesis of linear and branched 1,n-diborylalkanes. The reaction is thought to proceed by a frustrated Lewis pair type single-electron-transfer

    2-diyl-bridged A-frame complexes [Pt2X2(μ-1,2-B2(NMe2)2)(μ-dmpm)2]. X-ray crystallographic studies of these (BY)n-bridged complexes show structural trends depending on the steric demands of Y and the nature of X. Analysis of higher-order 31P NMR satellites provided information on JP–Pt and JPt–Pt coupling constants, the latter correlating with the Pt⋯Pt distance. All (di)boranediyl complexes also proved unstable

  • Hydroboration with Haloborane/Trialkylsilane Mixtures
    作者:Raman Soundararajan、Donald S. Matteson
    DOI:10.1021/om00009a018
    日期:1995.9
    Trialkylsilanes or dialkylsilanes react rapidly with boron trichloride in the absence of ethereal solvents or other nucleophiles to form unsolvated dichloroborane. If no substrate is present, dichloroborane disproportionates to trichloroborane and two geometric isomers of chloroborane dimer, which in turn yield monochlorodiborane and, slowly but irreversibly, diborane. All of the B-H compounds in the mixture except diborane are highly active hydroborating agents. With alkenes in the presence of sufficient boron trichloride, the products are alkyldichloroboranes. These are free from detectable contamination by dialkylchloroboranes unless more than 1 mol of hydride is present. Similar hydroboration of terminal acetylenes can be controlled to yield either (E)-1-(dichloroboryl)alkenes or 1,1-bis(dichloroboryl)alkanes, each free from significant contamination by the other. Alkyldichloroboranes with trialkylsilanes at 25 degrees C produce alkylmonochloroboranes, detected by B-11 NMR. 1,1-Bis(dichloroboryl)alkanes similarly yield 1,1-diborylalkane dimers. An alkylmonochloroborane can hydroborate a second alkene to form a dialkylchloroborane. For this purpose, differing alkyl groups may be introduced in either order, regardless of their relative steric properties. With 2 mol of trialkylsilane, alkyldichloroboranes are converted to alkylborane dimers. Boron tribromide and its bromoborane derivatives behave similarly to the chloro compounds in the examples tested.
