  • Hydroalumination versus Deprotonation of Alkynes with Sterically Demanding Substituents
    作者:Werner Uhl、Marcus Layh、Ines Rhotert、Agnes Wollschläger、Alexander Hepp

    Abstract

    Treatment of sterically highly shielded terminal alkynes, H-C≡C-aryl, with dialkylaluminium and dialkylgallium hydrides, R2E-H, afforded by hydrogen release dimeric dialkylelement alkynides with a four-membered E2C2 heterocycle independent of the bulk of the aryl groups. A rare example of a monomeric alkynylaluminium compound was only obtained with very bulky CH(SiMe3)2 groups attached to the metal atoms and by salt elimination reaction. The steric shielding by the bulky aryl groups did not prevent condensation reactions. Hydroalumination of 1-(trimethylsilyl)-2-(2,6- dimethylphenyl)ethyne using Me2Al-H resulted in a divinyl compound by elimination of trimethylaluminium

    摘要 用二烷基铝和二烷基氢化物 R2E-H 处理具有高度立体屏蔽的 H-C≡C-芳基末端炔,通过氢释放可得到具有独立于芳基基团的四元 E2C2 杂环的二聚二烷基元素炔。只有在属原子上连接了非常笨重的 CH(SiMe3)2 基团,并通过消盐反应,才能得到单体炔铝化合物的罕见实例。笨重芳基的立体屏蔽并不能阻止缩合反应。使用 ME2Al-H 对 1-(三甲基基)-2-(2,6- 二甲基苯基)乙炔进行氢化化,通过消除三甲基铝,可得到二乙烯基化合物。

    dialkylgallium hydrides R2GaH (R = Et, nPr, iPr, neopentyl, tBu) afforded the corresponding addition products with intact GaR2 groups and two or three alkenyl substituents. In all products the gallium atoms attacked those carbon atoms that are attached to the trimethylsilyl groups. The expected cis arrangement of gallium and hydrogen atoms at the CC double bonds was detected only with di(tert-butyl)gallium residues

  • New Insight into Hydrogallation Reactions:  Facile Synthesis of a Gallium-Bridged [3,3,3]-Cyclophane

    Treatment of 1,3,5-tris(3,3-dimethyl-1-butynyl)benzene, C6H3(C⋮C−CMe3)3, with di(neopentyl)gallium hydride, HGa(CH2CMe3)2, resulted in the addition of one Ga−H bond to each C⋮C triple bond (hydrogallation). Spontaneous condensation by the release of tri(neopentyl)gallium yielded a [3,3,3]-cyclophane derivative (1) with three tricoordinated Ga atoms in bridging positions.

  • New Aspects of Hydrogallation Reactions with Alkynes:  Simple Addition versus Formation of Cyclophanes
    作者:Werner Uhl、Sima Haddadpour、Madhat Matar
    DOI:10.1021/om050776e
    日期:2006.1.1
    Treatment of 1,4-bis(3,3-dimethyl-1-butynyl)benzene C6H4(C C-CMe3)(2) with 2 equiv of diethylgallium hydride resulted in addition of one Ga-H bond to each triple bond of the starting compound. Whereas in that case products of secondary reactions could not be isolated, dineopentylgalliurn hydride afforded a [3,3]-cyclophane derivative with two bridging Ga-CH2-CMe3 groups, which may be derived from the simple addition product by condensation and release of trineopentylgallium. A cis-arrangement of Ga and H was observed in all cases.
