    摘要:
    Cp(6,6-dmch)ZrX(2) 形式的分子(Cp = eta(5)-环戊二烯基,X = Cl、Br、I;6,6-dmch = eta(5)-6,6-二甲基环己二烯基) 已经合成,并且已经研究了分子和电子结构。这些分子允许直接比较相同高氧化态金属配合物中戊二烯基和环戊二烯基配体的键合和性质。与众所周知的 Cp(2)ZrX(2) 类似物不同,这些 Cp(6,6-dmch)ZrX(2) 分子颜色很深,表明前沿轨道的相对能量明显不同。同样不寻常的是,对于这些 Zr(IV) 配合物,到 6,6-dmch 戊二烯基配体的平均 Zr-C 距离比到环戊二烯基配体的平均 Zr-C 距离长约 0.1 A,与对 Zr 观察到的相反(II) 复合物 Cp(2,6,6-tmch)Zr(PMe(3))(2) (tmch = eta(5)-2,6, 6-三甲基环己二烯基),反映了取决于金属氧化态的键合有利性的戏剧性逆转。实验和计算结果表明

    Zr(C5H5)(6,6-dmch)(PMe3)2, an edge-bridged half-open zirconocene—synthesis, structure, and its reaction with C6H5C2SiMe3
    摘要:
    The synthesis and characterization of an edge-bridged half-open zirconocene, Zr(C5H5)(dmch)(PMe3)(2) (dmch = dimethylcyclo-hexadienyl), are described. As expected, the Zr-C bond distances for the dmch ligand are significantly shorter than those for the C5H5 ligand. The compound readily incorporates 2 equiv. of alkyne, with loss of the PMe3 ligands, leading to a zirconacyclopentadiene complex, so that the dmch ligand has remained intact.

  • Origin of 1,4-Regiochemistry in the Dicouplings of Ketones with 6,6-Dimethylcyclohexadienyl Complexes of Titanium and Zirconium:  A Mechanism Arising from Five-Electron Donation by Alkoxide Ligands

    proposal of a new mechanism for these reactions, in which an alkoxide ligand, generated from a coupling of the initially incorporated ketone, serves as a formal five-electron donor, thereby altering the mode of coordination of the diene fragment. This proposal has been supported by the characterization of a mono(benzophenone) coupling product of Ti(C5H5)(6,6-dmch)(PMe3). This coupling product possessed
    在对Ti(C 5 H 5)(6,6-dmch)(PMe 3)(dmch =二甲基环己二烯基)与酮的偶联反应的较早研究中,最初形成的属络合物无法分离,但解后却空前分离出1,4-二偶合产物。为了进一步了解这种区域化学的起源,类似物Zr(C 5 H 5)(6,6-dmch)(PMe 3)2的反应,用丙酮进行了研究。可以分离出固体二聚体产物并对其结构进行表征,这表明这两种丙酮均已偶联,并且具有不同寻常的1,4-区域化学。然后这需要提出用于这些反应的新机理的建议,其中由最初掺入的酮的偶合产生的醇盐配体用作正式的五电子供体,从而改变二烯片段的配位方式。Ti(C 5 H 5)(6,6-dmch)(PMe 3)单(二苯甲酮)偶联产物的表征为该建议提供了支持)。此偶联产物具有两个大的Ti-O-C的角度,指示至少其中醇盐配体用作五给电子体的共振形式的局部贡献的和预期η 2 -二烯协调。
  • Reactions of Zr(C5H5)(6,6-dmch)(PMe3)2 and Zr(6,6-dmch)2(PMe3)2 (dmch=dimethylcyclohexadienyl) with CO and alkynes

    The reactions of Zr(C5H5)(6,6-dmch)(PMe3)(2) and Zr(6,6-dmch)(2)(PMe3)(2) (dmch = dimethylcyclohexadienyl) with CO lead to the selective replacement of one PMe3 ligand by CO. Both carbonyl complexes have been structurally characterized. Additionally, the reaction of the latter complex with PhC2SiMe3 leads to a similar replacement of one PMe3 ligand, involving simple coordination of the alkyne, rather than any coupling to the dmch ligand.
