    作者:Marcial Moreno-Mañas、Roser Pleixats、Anna Serra-Muns
    DOI:10.1055/s-2006-948173
    日期:2006.11
    The combination of a bulky aliphatic phosphine, e.g. tricyclohexylphosphine or the tetrafluoroborate salt of tri-tert-butylphosphine, with the Pd(0) complex of a 15-membered triolefinic macrocycle is an excellent catalyst for the Suzuki cross-coupling of aryl and heteroaryl bromides and chlorides. The palladium can be recovered in the form of the initial complex.

    tert-butyl hydroperoxide (tBuOOH) were activated by various oxo and peroxo complexes of molybdenum, tungsten, and vanadium as catalysts for the sulfoxidation of thianthrene 5-oxide (SSO). A screening of a number of phosphane oxide and amine oxide ligands revealed that BTSP was most efficiently activated by the [MoO5(OPtBu3)] complex. The best results for tBuOOH as oxygen source were achieved with the

  • A new family of monocyclopentadienyl organoscandium <i>bis</i>-alkyls supported by a bulky trialkylphosphine oxide ancillary
    作者:Lee D Henderson、Glen D MacInnis、Warren E Piers、Masood Parvez
    DOI:10.1139/v03-157
    日期:2004.2.1

    Treatment of the oligomeric compound [Cp*ScCl2]n (Cp* = C5Me5) with tri-tert-butylphosphine oxide in THF leads to the monocyclopentadienyl scandium dichloride [Cp*(t-Bu3P=O)ScCl2] as a monomeric, THF-free solid in 72% yield. This compound can be alkylated with MeLi to give the corresponding dimethyl derivative, [Cp*(t-Bu3P=O)ScMe2], 1. The crystal structures of these two compounds have been done and reveal a three-legged piano stool geometry about the scandium center. The coordinated phosphine oxide ligand exchanges with free donor in both compounds via an associative mechanism, as indicated by the activation parameters (ΔH‡ = 6.4–8.4 kcal mol–1-; ΔS‡ = –22.5 to –26.6 eu). Thus, the Cp*(t-Bu3P=O) ligand set provides a stable platform for organoscandium chemistry. This was demonstrated by the activation of 1 by treatment with B(C6F5)3 to form the fully characterized contact ion pair [Cp*(t-Bu3P=O)ScMe]+[MeB(C6F5)3]–, 2, which is an active ethylene polymerization catalyst.Key words: organoscandium compounds, olefin polymerization, cationic complexes.

    将[Cp*ScCl2]n (Cp* = C5Me5)与三叔丁基膦氧在THF中反应,得到单环戊二烯基钪二氯化物[Cp*(t-Bu3P=O)ScCl2],产率为72%。这种化合物可以通过与MeLi烷基化来得到相应的二甲基衍生物[Cp*(t-Bu3P=O)ScMe2]。这两种化合物的晶体结构已经确定,显示出环境钪中心周围的三脚架几何构型。配位的膦氧配体通过一个联合机制与两种化合物中的自由给体交换,这是由活化参数(ΔH‡ = 6.4–8.4 kcal mol–1; ΔS‡ = –22.5 to –26.6 eu)所指示的。因此,Cp*(t-Bu3P=O)配体组提供了一个稳定的有机钪化学平台。通过将1与B(C6F5)3处理,形成完全表征的接触离子对[Cp*(t-Bu3P=O)ScMe]+[MeB(C6F5)3]–,这是一种活性乙烯聚合催化剂。关键词:有机钪化合物、烯烃聚合、阳离子配合物。
