  • Bestimmung der ionenpaar-basizitǎt von lithium- und kaliumamiden

    Ion pair basicities of lithio and potassio salts of some secondary amines were determined by equilibration with benzyl compounds. With these bases it is possible to span a range of about 19 pK-units from pK = 27 up to 46. The structural dependence of thermodynamic as well as kinetic basicity is discussed. Some new effective amide bases for preparative purposes are recommended. For the first time the

    ligand are reactive toward aromatic N-heterocycles by mediating their coupling and, in a few cases, the cleavage of their C-N bonds. When these complexes reacted with 2,2'-bipyridine or isoquinoline, they facilitated the alkyl migration of the benzyl ligand onto the pyridine ring, a process accompanied by the dearomatization of the N-heterocycle. The products of the alkyl-transfer reactions act as hydrogen
    二茂铁二酰胺配体支持的第 3 族 (Sc, Y, Lu, La) 苄基复合物通过介导它们的偶联以及在少数情况下其 CN 键的断裂对芳香族 N-杂环具有反应性。当这些配合物与 2,2'-联吡啶异喹啉反应时,它们促进了苄基配体的烷基迁移到吡啶环上,这一过程伴随着 N-杂环的脱芳构化。在芳族 N-杂环、酮和偶氮苯存在下,烷基转移反应的产物充当氢供体。实验和计算研究表明,氢转移是通过协同机制发生的。还报道了脱芳构化的、烷基取代的异喹啉配合物的有趣歧化反应。
  • Concerted C−N and C−H Bond Formation in a Magnesium-Catalyzed Hydroamination

    tris(4,4-dimethyl-2-oxazolinyl)phenylborate) is an active precatalyst for intramolecular hydroamination/cyclization at 50 °C. The empirical rate law of -d[substrate]/dt = k'(obs)[Mg](1)[substrate](1) and Michaelis-Menten-type kinetics are consistent with a mechanism involving reversible catalyst-substrate association prior to cyclization. The resting state of the catalyst, To(M)MgNHCH(2)CR(2)CH(2)CH═CH(2)
    配位饱和 To(M)MgMe (1; To(M) = tris(4,4-二甲基-2-恶唑啉基)苯基硼酸酯)是一种在 50 °C 下分子内加氢胺化/环化的活性预催化剂。-d[底物]/dt = k'(obs)[Mg](1)[底物](1) 和 Michaelis-Menten 型动力学的经验速率定律与涉及可逆催化剂 - 底物结合之前的机制一致环化。催化剂的静止状态 To(M)MgNHCH(2)CR(2)CH(2)CH=CH(2) [R = Ph, Me, -(CH(2))(5)-] 是可分离但分离的基烯烃在 50 °C 下不会发生单分子环化。然而,添加痕量底物允许发生环化。因此,我们提出了一种包含协调的 CN 键形成和 NH 键裂解的两底物、六中心过渡态,作为催化循环的周转限制步骤。

  • Scandium Alkyl Complexes Supported by a Ferrocene Diamide Ligand
    作者:Colin T. Carver、Marisa J. Monreal、Paula L. Diaconescu
    DOI:10.1021/om7007277
    日期:2008.2.1
    Synthesis of a scandium dimethylbenzyl complex supported by a ferrocene diamide ligand was accomplished by alkane elimination from Sc(CH(2)Xy-3,5)(3)(THF)(2). The scandium dimethylbenzyl complex Sc(fc[NSi(tBu)Me-2](2))(CH(2)Xy-3,5)(THF), 2-(CH(2)Xy-3,5)(THF), was used as a starting material for the synthesis of the corresponding chloride-bridged dimer, (2-CI)(2), which, in turn, led to a scandium bis(neo-pentyl) ate salt, Li[2Np(2)]. Attempts to remove the coordinated THF molecule from 2-(CH(2)Xy-3,5)(THF) with AlMe3 led to the isolation of a scandium methyl complex with two coordinated AlMe3 molecules, 2-Me(AlMe3)(2). Compound 2-Me(AlMe3)(2) led to a scandium methyl complex, 2-Me(THF)(2), by stirring in THF. All ferrocene diamido compounds were characterized by X-ray crystallography. DFT calculations on model compounds were used to explain the stability of the compounds synthesized and to probe the existence of an iron-scandium interaction. Compounds 2-(CH(2)Xy-3,5)(THF) and 2-Me(AlMe3)(2) polymerize L-lactide.
