    Carbonyl Insertions into Metal-Nitrogen Bonds of Group 4 Dialkylamido Complexes. X-ray Structure of Cp*(Me2N)2Ti[O(Me2N)C]W(CO)5
    摘要:
    [Cp*M(NMe(2))(3)] [Cp* = eta(5)-C(5)Me(5); 1, M = Ti; 2, M = Zr] reacts with metal carbonyls, M'(CO)(n) (n = 6, M' = Cr, Mo, W; n = 5, M' = Fe), to give the corresponding insertion products, Cp*(Me(2)N)(2)M[O(Me(2)N)C]M'(CO)(n-1) (M = Ti; 3, M' = W; 4, M' = Mo; 5, M' = Cr; 6, M' = Fe; M = Zr; 7, M' = W; 8, M' Mo; 9, M' = Cr; 10, M' = Fe), in good yield. When complexes 3-5 were heated at 80 degrees C in toluene for several days, Cp*Ti(mu-NMe(2))(2)[O(NMe(2))C]M'(CO)(3) (11, M' = W; 12, M' = Mo; 13, M' = Cr) were obtained. However, heating 6 under the same conditions gave Cp*(Me(2)N)Ti[O(Me(2)N)C]Fe-2(CO)(3) (14). Reactions of 12 with CO and Bu(t)-NC have been carried out, giving compound 4 in the first case-and Cp*(Me(2)N)2(T)i[O(Me(2)N)C]Mo(CO)(3)(CNBu(t))(2) (15) in the second. The structure of 3 has been proved unequivocally by a X-ray diffraction study (space group P2(1), a = 8.828(2) Angstrom, b = 13.001(4) Angstrom, c = 12.045(2) Angstrom, beta = 98.22(2)degrees, Z = 2, R(1) = 0.044 and wR(2) = 0.109). 3 consists of two moieties, Cp*Ti(NMe(2))(2) and W(CO)(5), bridged by a [O(Me(2)N)C] unit where the oxygen atom is bound to the oxophilic titanium atom, while the carbon is forming a Fischer carbene-like complex with tungsten.

  • Catalytic alkene cyclohydroamination via an imido mechanism

    DOI:10.1039/b718373a
    日期:——
    Chiral-at-metal half-sandwich diamide complexes catalyse enantioselective cyclohydroamination of aminoalkenes at unexpectedly high rates given their high coordination number and steric bulk; substantial evidence is presented which argues against the established σ-bond insertion process and is strongly indicative of an imido [2+2] cycloaddition mechanism.

    Mono-, di- and trinuclear zirconium hydride species have been isolated in the treatment of amido complexes [Zr(η5-C5Me5)(NMe2)nCl3−n] (n = 3, 1) with amine–borane adducts NHR2BH3 (R2 = Me2, HtBu). The reactions involve the formation of amidoborane ligands with Zr⋯H–B interactions which readily undergo β-hydride elimination to give hydride functions.

    hydroamination/cyclization of primary aminoalkenes by catalysts based on Cp*LZr(NMe(2))(2) (L = κ(2)-salicyloxazoline) is investigated in a range of kinetic, stoichiometric, and structural studies. The rate law is found to be d[substrate]/dt = k[catalyst](1)[substrate](0) for all catalysts and aminoalkenes studied. The overall rate is similar for formation of five- and six-membered rings, and a substantial
    在一系列动力学、化学计量和结构研究中研究了基于 Cp*LZr(NMe(2))(2)(L = κ(2)-杨唑啉)的催化剂对伯烃进行加氢胺化/环化的机制。对于所研究的所有催化剂烃,发现速率定律为 d[底物]/dt = k[催化剂](1)[底物](0)。五元环和六元环的形成总体速率相似,并且观察到大量的 KIE (k(H)/k(D)),表明 NH 键断裂参与了速率决定步骤 (RDS ) 不是闭环。值得注意的是,该反应在 THF 中以与在甲苯中相同的速率进行,但添加的不可环化胺会减慢反应速度,这表明虽然属在 RDS 中不充当路易斯酸,但涉及活化的底物。同样与其他催化剂相比,增加空间体积提高了速率,并且通过 X 射线晶体学研究了其起源。从八项独立的动力学研究中提取的热力学参数表明,在此过程中,中度有序(ΔS(双匕首)= -13 至 -23 cal/K·mol)和大量的整体键断裂(ΔH(双匕首)=
