  • Hetero-dehydrocoupling of silanes and amines by heavier alkaline earth catalysis
    作者:Michael S. Hill、David J. Liptrot、Dugald J. MacDougall、Mary F. Mahon、Thomas P. Robinson
    DOI:10.1039/c3sc51797g

    The homoleptic alkaline earth hexamethyldisilazides, [MN(SiMe3)2}2]2 (1: M = Mg; 2: M = Ca; 3: M = Sr), have been demonstrated as active pre-catalysts for the cross-dehydrocoupling of Si–H and N–H bonds under mild (25–60 °C) conditions. The reactions are applicable to the coupling of a wide variety of amine and silane substrates and are proposed to occur via a sequence of discrete Si–H/M–N and N–H/M–H metathesis steps. Whereas reactions of dialkyl group 2 species with 2,6-di-iso-propylaniline and phenylsilane delivered a series of well-defined compounds consistent with this rationale, kinetic analysis of the cross-coupling of diethylamine with diphenylsilane provided evidence for a more complex and subtly variable mechanistic landscape. Although reactions performed with all three pre-catalysts presented a number of common features, in every case the calcium species, 2, was found to provide notably superior catalytic activity, an order of magnitude higher than both 1 and 3 and in excess of many previously described benchmark transition metal- or f-element-mediated processes. Variations in overall reaction order, mode of pre-catalyst activation and the nature of the rate determining process are postulated to arise as a consequence of the marked change in M2+ radius and resultant charge density as group 2 is descended.
    均配位碱土金属六甲基二硅氨基化合物 [MN(SiMe3)2}2]2 (1: M = Mg; 2: M = Ca; 3: M = Sr) 已被证明是在温和(25–60 °C)条件下进行 Si–H 和 N–H 键交叉脱氢耦合的活性前催化剂。这些反应适用于各种胺和硅烷底物的耦合,推测通过一系列离散的 Si–H/M–N 和 N–H/M–H 置换步骤进行。尽管与 2,6-二异丙基苯胺和苯基硅烷反应的二烷基物种 2 给予了一系列与此推断一致的定义良好的化合物,但在二乙胺与二苯硅烷交叉耦合的动力学分析提供了更为复杂且微妙变化的反应机制证据。虽然使用三种前催化剂进行的反应表现出一些共同特征,但在每种情况下,钙物种 2 显示出明显优越的催化活性,显著高于 1 和 3,并且超出了许多先前描述的基准过渡金属或 f 元素介导的过程。整体反应级数、前催化剂活化方式及速率决定过程的性质变化被推测为由于 M2+ 半径的显著变化及随族下降而导致的电荷密度变化。

    cross‐dehydrogenative coupling of silanes with a range of primary and secondary amines to yield silylamines in high yields (82–100 %) under mild reaction conditions. The catalytic activity and selectivity of the rareearthmetal silylamides are modulated by altering the steric bulk of the NHC.

    Silicon-oxygen and silicon-nitrogen heterodehydrocoupling catalyzed by the commercially available cyclopentadienyl dicarbonyl iron dimer [CpFe(CO)2]2 (1) under photochemical conditions is reported. Reactions between alcohols and PhSiH3 with catalytic 1 under visible-light irradiation produced silyl ethers quantitively. Reactions between either secondary or tertiary silanes and alcohols also produced

  • Dehydrocoupling reactions of amines with silanes catalyzed by [(Et2N)3U][BPh4]
    作者:Jia Xi Wang、Aswini K Dash、Jean Claude Berthet、Michel Ephritikhine、Moris S Eisen

    日期:2000.9
    Dehydrocoupling reactions of primary amines RNH2 with PhSiH3 were catalyzed by [(Et2N)3U][BPh4] to give the corresponding aminosilanes PhSiH3−n(NHR)n (n=1–3), the relative yields of the products were found to be dependent on the experimental conditions and on the nature of R. For a primary silane (PhSiH3), the reactivity of RNH2 follows the order primary>secondary>tertiary. Similar dehydrocoupling

  • Si–N Heterodehydrocoupling with a Lanthanide Compound
    作者:Michael P. Cibuzar、Rory Waterman
    DOI:10.1021/acs.organomet.8b00372
    日期:2018.12.10
    [LaN(SiMe3)2}3THF2] (1) is an effective precatalyst for the heterodehydrocoupling of silanes and amines. Coupling of primary and secondary amines with aryl silanes was achieved with a loading of 0.8 mol % of [LaN(SiMe3)2}3THF2]. With primary amines, generation of tertiary and sometimes quaternary silamines was facile, often requiring only a few hours to reach completion, including new silamines Ph3Si(nPrNH)
    [La N(SiMe 3)2 } 3 THF 2 ](1)是用于硅烷和胺的杂脱氢偶联的有效预催化剂。伯胺和仲胺与芳基硅烷的偶联以0.8摩尔%的[La N(SiMe 3)2 } 3 THF 2 ]的负载量实现。使用伯胺时,叔硅胺(有时是季胺)的生成变得容易,通常只需几个小时即可完成反应,包括新的硅胺Ph 3 Si(n PrNH)和Ph 3 Si(iPrNH)。仲胺也可用于杂脱氢偶联,尽管它们通常需要更长的反应时间,在某些情况下还需要更高的反应温度。这项工作扩展了f嵌段配合物在杂脱氢偶联催化中的用途。
