    Influence of SiMe3 Substituents on Structures and Hydrosilylation Activities of ((SiMe3)1or2-Indenyl)Ni(PPh3)Cl
    摘要:
    This report examines the effect of substituents R on structures and reactivities of the complexes (R-Ind)Ni(PPh3)Cl (R-Ind = 1-Me-indenyl, 1; 1-SiMe3-indenyl, 2; 1,3-(SiMe3)(2-) indenyl, 3). NMR studies indicate that a relatively facile dissociation of PPh3 takes place in solutions of complex 3 (DeltaG(double dagger) approximate to 10 kcal/mol in C6D6) but not those of complexes 1 and 2, implying that the presence of Ind substituents at the 1- and 3-positions can influence the kinetic lability of PPh3. X-ray analyses have also shown that the PPh3 ligand and the SiMe3 group adjacent to it in complex 3 experience some steric repulsion, which is manifested in angular deformations (out-of-plane bending of the SiMe3 group by about 0.56-0.65 Angstrom and 5 - 10degrees variations in the P-Ni-Cl and P-Ni-C3 angles) and a somewhat longer Ni-P bond (ca. 2.19 Angstrom). Reactivity studies have shown that complexes 1-3 are effective precatalysts for the addition of PhSiH3 to styrene in the presence of the cationic initiator NaBPh4; alpha-addition of the silyl moiety takes place regioselectively to give PhCH(Me)(SiPhH2). The catalytic activities depend on the styrene:PhSiH3 ratio but not the Ind substituents; thus, catalytic turnover numbers increase from ca. 75 with a 1:1 ratio to ca. 95 with a 1:1.5 ratio for all three precursors. The hydrosilylation can also proceed in the absence of initiator, but in this case the activities are strongly dependent on Ind substituents, increasing in the order I-Me-Ind much less than 1-SiMe3-Ind < 1,3-(SiMe3)(2)-Ind.

    Abstract Reaction between carbanions and the cationic cyclooctadiene iridium complex, [Ir(COD)(PMe 3 ) 3 ]Cl, gives rise to one of three different products depending on the nature of the carbanion. For resonance stabilized carbanions (indenyl, allyl, benzyl), the products are (2-substituted cyclooct-5-en-1-yl)tris(trimethylphosphine)iridium complexes derived from nucleophilic attack of the carbanion on one

  • Phenylsilane dehydrocoupling and addition to styrene catalyzed by (R-indenyl)Ni(phosphine)(methyl) complexes
    作者:Yaofeng Chen、Davit Zargarian
    DOI:10.1139/v08-132
    日期:2009.1.1

    This report describes the synthesis and characterization of the Ni–Me complexes (R-indenyl)Ni(PR′3)Me (R = 1-i-Pr, 1-SiMe3, and 1,3-(SiMe3)2; R′= Me, Ph) and outlines their catalytic reactivities in the dehydrogenative oligomerization of PhSiH3 and its addition to styrene in the absence of initiators/activators. Observation of higher hydrosilylation activities for PPh3-based compounds featuring bulky substituents on the indenyl ligand confirms earlier suggestions that phosphine dissociation is an important component of the catalytic cycle for this reaction. In contrast, oligomerization of PhSiH3 is more facile with PMe3-based precursors and independent of the steric bulk of the indenyl ligand, implying that this reaction does not involve phosphine dissociation. These conclusions are consistent with the variable-temperature 1H NMR spectra of 1,3,-(SiMe3)2-indenyl}Ni(PR′3)Me and various structural parameters observed in the solid-state structures of 1,3,-(SiMe3)2-indenyl}Ni(PPh3)Me, 1,3,-(SiMe3)2-indenyl}Ni(PMe3)Cl, and 1-SiMe3-indenyl}Ni(PMe3)Me.Key words: nickel-indenyl complexes, hydrosilylation, hydrosilane oligomerization.

    本报告描述了 Ni-Me 复合物 (R-indenyl)Ni(PR′3)Me 的合成和特性(R = 1-i-Pr、1-SiMe3 和 1,3-(SiMe3)2;R′= Me、Ph),并概述了它们在 PhSiH3 的脱氢低聚过程中的催化反应活性,以及在没有引发剂/活化剂的情况下与苯乙烯的加成反应。观察到配体上具有大取代基的 PPh3 基化合物具有更高的氢化活性,这证实了之前的观点,即膦解离是该反应催化循环的重要组成部分。相比之下,PhSiH3 的低聚作用在使用 PMe3 前体时更为容易,且不受配体立体体积的影响,这意味着该反应不涉及膦解离。这些结论与1,3,-(SiMe3)2-基}Ni(PR′3)Me 的变温 1H NMR 光谱以及在1,3,-(SiMe3)2-基}Ni(PPh3)Me、1,3,-(SiMe3)2-基}Ni(PMe3)Cl 和1-SiMe3-基}Ni(PMe3)Me 的固态结构中观察到的各种结构参数是一致的。关键词:-基配合物、氢化、氢硅烷低聚。

    A group of new trimethylsilyl indenyl derivatives of molybdenum is reported, starting from the allyl compound TMSIndMo(η3-C3H5)(CO)2 [TMSInd=η3-SiMe3C9H6]. The novel allyl Mo(II) complex, which is synthesized by the reaction of Mo(η3-C3H5)(CO)2(NCMe)2Cl with Li(TMSInd) in THF, is the precursor to trimethylsilyl indenyl derivatives.

    corresponding zirconocene dichlorides are presented. The rac- and meso-diastereomers of the 1-substituted zirconocene dichlorides can in most cases be separated. Instable zirconocenes were observed for certain substitution patterns. Two of the obtained zirconocene dichlorides, bis[2-(dimethylsilyl)indenyl]zirconium dichloride (4a) and bis[2-(trimethylsilyl)indenyl]zirconium dichloride (4b), were characterised
    介绍了系统合成的1-和2-取代的甲硅烷,在甲硅烷基部分上具有多种取代方式,以及它们相应的二茂化物。在大多数情况下,可以将1-取代的茂二化物的外消旋和内消旋非对映异构体分开。对于某些取代模式,观察到不稳定的茂。通过单晶X射线衍射对获得的二氧化锆中的两个二化双[2-(二甲基甲硅烷基)基]二(4a)和双[2-(三甲基甲硅烷基)基]二(4b)进行表征。基于DFT结果,两种化合物在几何上是相似的,即甲硅烷基部分上的另外的甲基仅影响构象能谱。因此,在与乙烷的均聚研究中,其催化剂性能的差异归因于构象控制。对于其余的配合物,就催化剂性能而言,空间上要求较低的甲硅烷基似乎是有利的。所有的2-异构体均具有比未取代的双[基]二/ MAO体系更低的聚合活性。奇怪的是,发现rac-双[1-(二甲基苯基甲硅烷基)基]二/ MAO体系是乙烯均聚反应中活性最高的催化剂。

    Evaluation of the steric and electronic influence of a family of silyl- and alkyl-substituted indenyl ligands on zirconium and iron centers has been accomplished by a combination of X-ray diffraction, IR spectroscopy, solution NMR dynamics, and electrochemical measurements.

    通过结合X射线衍射,IR光谱,溶液NMR动力学和电化学测量,完成了对甲硅烷基和烷基取代的配体中心的空间和电子影响的评估。三种四取代的双茂二化物络合物已通过X射线衍射进行了表征,并采用了gauche配体构象,从而使相邻环上的叔取代基之间的相互作用最小化。在两种相应的化合物中也观察到相似的固态构象。通过测量二羰基衍生物的CO拉伸频率,可以评估每个中心的电子环境。简单的感应效应控制着每个茂的电子性质,其中甲硅烷基是相对吸电子的,而烷基是供电子的。对于受阻最严重的二茂二羰基衍生物,通过红外光谱已检测到三个振动上不同的旋转异构体。通过类似温度的配合物系列通过可变温度NMR光谱学和电化学对这些立体电子参数的独立评估提供了配体的相同相对顺序。
