    examples of group 14, group 6 and group 10 complexes from lithiated or chlorinated 4,4-dimethyl-2-(2-thienyl) oxazoline or its N-alkylated analogs. Two of the product types (2and 5) can be classified as a-thio or remote carbene complexes, depending on the position (3- or 5-) of attachment to the substituted thiophene ring.

  • <sup>31</sup>P chemical shift anisotropies of trimethyl- and triphenylphosphine-substituted Group 6 metal pentacarbonyl complexes
    作者:Jordan H Wosnick、Frederick G Morin、Denis FR Gilson
    DOI:10.1139/v98-167
    日期:1998.9.1

    The 31P chemical shift tensor components and anisotropies of the trimethyl- and triphenylphosphine complexes of the group 6 metal pentacarbonyls, M(CO)5PR3 (M = Cr, Mo, W and R = Me, Ph), have been measured using solid-state CP-MAS 31P NMR spectroscopy. For the trimethylphosphine derivatives, the chemical shift tensors have near axial symmetry and the shift tensor components are in reasonable agreement with the calculated values for the chromium and molybdenum complexes. In the triphenylphosphine complexes, the tensors are asymmetric due to the different torsion angles of the phenyl rings. The trend to higher shielding of the isotropic 31P chemical shifts on descending group 6 arises from changes in the perpendicular components of the shift tensor. The one-bond coupling constants, 1J(95/97Mo-31P), for the trimethyl- and triphenylphosphine complexes are 129 and 133 Hz, respectively.Key words: chemical shift anisotropy, phosphines, chromium, molybdenum, tungsten.

    三甲基和三苯基膦配合物的31P化学位移张量分量和各向异性已经使用固体CP-MAS 31P NMR光谱学进行了测量。对于三甲基膦生物化学位移张量具有近轴对称性,并且位移张量分量与配合物的计算值基本一致。在三苯基膦配合物中,张量是不对称的,这是由于苯环的扭转角不同。下降到第6族元素时,各向异性31P化学位移的屏蔽趋势是由于位移张量的垂直分量的变化。对于三甲基和三苯基膦配合物的一键耦合常数,1J(95/97Mo-31P),分别为129和133赫兹。关键词:化学位移各向异性,膦化合物,

    Abstract The ultraviolet photoelectron spectra of Cr(CO) 5 (4-RPyr) have been measured, and the IP's observed below 12 eV are discussed. Bands found in the region 7-8 eV are assigned to ionization from the chromium d orbitals. The IP values are shown to increase with the increasing electron acceptor nature of the ring substituents. The remaining bands below 12 eV are assigned to the pyridine orbitals
    摘要测量了Cr(CO)5(4-RPyr)的紫外光电子光谱,并讨论了在12 eV以下观察到的IP。在7-8 eV区域中发现的能带被分配给d轨道的电离。IP值显示出随着环取代基的电子受体性质的增加而增加。低于12 eV的其余谱带分配给吡啶轨道。观察到未络合的吡啶的IP值在络合时增加,并且比较了与Cr(CO)5和BH 3部分的络合作用。

    halogen derivatives is demonstrated. The reaction of 2a with RBr (R = PhCH(2), HC triple bond CCH(2)) produces the RX addition products [(R)(Br)As(Cr(CO)(5))(2)](-) (R = PhCH(2), 3; R = C(3)H(3), 4), while the treatment of 2b with RX (RX = PhCH(2)Br or HC triple bond CCH(2)Br, CH(3)(CH(2))(5)C(O)Cl) forms the halo-substituted complexes [XSb(Cr(CO)(5))(3)](2-) (X = Br, 5; X = Cl, 6). Moreover, the dihaloantimony

    In addition to the facile pyramidal atomic inversion of the metal-co-ordinated sulphur and selenium atoms, a novel 1,3-metal shift between the two different ligand atoms occurs. From static and dynamic n.m.r. studies the relative populations of sulphur- and selenium-bonded species have been obtained, along with the activation energy for both S → Se and Se → S metal shifts Energy profiles for these
    单核络合物[M(CO)5(MeSeCH 2SMe)](M = Cr,Mo或W)已制备,并以S→M和Se→M键均存在的异构体形式存在于溶液中。除了属配位的原子容易进行字塔形原子反转外,两个不同的配体原子之间还发生了新的1,3-属转移。通过静态和动态核磁共振研究,已经获得了键和键物种的相对种群,以及S→Se和Se→S属位移的活化能,这1,3个位移的能谱揭示了两者之间的区别。键和键异构体之间的基态能量,基本上量化了S→M和Se→M键之间的键能差。这样的值不容易获得。
