  • Application of molybdenum bis(imido) complexes in ethylene dimerisation catalysis
    作者:William R. H. Wright、Andrei S. Batsanov、Antonis M. Messinis、Judith A. K. Howard、Robert P. Tooze、Martin J. Hanton、Philip W. Dyer

    In combination with EtAlCl2 (Mo : Al = 1 : 15) the imido complexes [MoCl2(NR)(NR′)(dme)] (R = R′ = 2,6-Pri2–C6H3 (1); R = 2,6-Pri2–C6H3, R′ = But (3); R = R′ = But (4); dme = 1,2-dimethoxyethane) and [Mo(NHBut)2(NR)2] (R = 2,6-Pri2–C6H3 (5); R = But (6)) each show moderate TON, activity, and selectivity for the catalytic dimerisation of ethylene, which is influenced by the nature of the imido substituents. In contrast, the productivity of [MoCl2(NPh)2(dme)] (2) is low and polymerisation is favoured over dimerisation. Catalysis initiated by complexes 1–4 in combination with MeAlCl2 (Mo : Al = 1 : 15) exhibits a significantly lower productivity. Reaction of complex 5 with EtAlCl2 (2 equiv.) gives rise to a mixture of products, while addition of MeAlCl2 affords [MoMe2(N–2,6-Pri2–C6H3)2]. Treatment of 6 with RAlCl2 (2 equiv.) (R = Me, Et) yields [Mo(μ-N–But}AlCl2)2] (7) in both cases. Imido derivatives 1 and 3 react with Me3Al and MeAlCl2 to form the bimetallic complexes [MoMe2(NR}AlMe2μ-Cl})(NR′)] (R = R′ = 2,6-Pri2–C6H3 (8); R = 2,6-Pri2–C6H3, R′ = But (10)) and [MoMe2(NR}AlCl2μ-Cl})(NR′)] (R = R′ = 2,6-Pri2–C6H3 (9); R = 2,6-Pri2–C6H3, R′ = But (11)), respectively. Exposure of complex 8 to five equivalents of thf or PMe3 affords the adducts [MoMe2(N–2,6-Pri2–C6H3)2(L)] (L = thf (12); L = PMe3 (13)), while reaction with NEt3 (5 equiv.) yields [MoMe2(N–2,6-Pri2–C6H3)2]. The molecular structures of complexes 5, 9 and 11 have been determined.
    结合EtAlCl2(Mo : Al = 1 : 15),酰胺配合物[MoCl2(NR)(NR′)(dme)](R = R′ = 2,6-Pri2–C6H3(1);R = 2,6-Pri2–C6H3,R′ = But(3);R = R′ = But(4);dme = 1,2-二甲氧基乙烷)和[Mo(NHBut)2(NR)2](R = 2,6-Pri2–C6H3(5);R = But(6))各自显示出中等的重氮乙烯催化二聚反应的TON、活性和选择性,这受到酰胺取代基性质的影响。相比之下,[MoCl2(NPh)2(dme)](2)的产率较低,更倾向于聚合而非二聚。结合MeAlCl2(Mo : Al = 1 : 15)的1–4配合物引发的催化反应显示出明显较低的产率。5配合物与EtAlCl2(2 equiv.)反应生成产物混合物,而加入MeAlCl2则得到[MoMe2(N–2,6-Pri2–C6H3)2]。6配合物与RAlCl2(2 equiv.)(R = Me, Et)反应在两种情况下均生成[Mo(μ-N–But}AlCl2)2](7)。酰胺衍生物1和3与Me3Al和MeAlCl2反应形成双金属配合物[MoMe2(NR}AlMe2μ-Cl})(NR′)](R = R′ = 2,6-Pri2–C6H3(8);R = 2,6-Pri2–C6H3,R′ = But(10))和[MoMe2(NR}AlCl2μ-Cl})(NR′)](R = R′ = 2,6-Pri2–C6H3(9);R = 2,6-Pri2–C6H3,R′ = But(11))。将8配合物暴露于五个当量的thf或PMe3,得到加合物[MoMe2(N–2,6-Pri2–C6H3)2(L)](L = thf(12);L = PMe3(13)),而与NEt3(5 equiv.)反应则得到[MoMe2(N–2,6-Pri2–C6H3)2]。5、9和11配合物的分子结构已被确定。

    作者:Klaus Knabel、Heinrich Nöth

    日期:2005.10.1
    tmpAlBr2 (tmp = 2,2,6,6-tetramethylpiperidino) was prepared from AlBr3 and tmp2AlBr at 90 °C in the absence of a solvent, but could not be crystallised from toluene or hexane because it reacted with the solvents to form tmpH·AlBr3 in high yield. tmpH·AlMeCl2, obtained from the components, decomposes at elevated temperatures but no tmpAlCl2 could be isolated. Attempts to generate the cation [tmp-Al-tmp]+
    tmpAlBr2 (tmp = 2,2,6,6-四甲基哌啶基) 由 AlBr3 和 tmp2AlBr 在 90 °C 下无溶剂制备,但不能从甲苯或己烷中结晶,因为它与溶剂反应形成 tmpH· AlBr3 收率高。从组分中获得的 tmpH·AlMeCl2 在升高的温度下会分解,但无法分离出 tmpAlCl2。尝试通过用 B(C6F5)3、Ph3C(SnCl5) 或 SbCl5 或从 tmp2AlR (R = Me, Ph) 和 B(C6F5)3 的卤化物提取从 tmp2AlBr 或 tmp2AlCl 生成阳离子 [tmp-Al-tmp]+失败的。在 THF 中用 BH3 处理 tmp-B=P(tBu)AlBr3 时发生了意想不到的反应,导致形成 [AlBr2(thf)4][AlBr4]。尝试从 tBu2AlBr 和 Li(tmp) 合成 tBu2Al(tmp) 得到的产物在干冰温度下暴露于 CO2
  • Carbometalation Reactions of Diphenylacetylene and Other Alkynes with Methylalanes and Titanocene Derivatives
    作者:Ei-ichi Negishi、Denis Y. Kondakov、David E. Van Horn
    DOI:10.1021/om960879k
    日期:1997.3.1
    The reaction of PhC⋮CPh with methylalanes and titanocene derivatives is multimechanistic. In cases where 1:1 mixtures of Me3Al or Me2AlCl with Cl2TiCp2 or MeTiCp2Cl are used, the reaction proceeds exclusively via methyltitanation, which needs to be promoted by a methylalane but is stoichiometric in both Ti and Al. The product of methyltitanation is ≥98% stereoisomerically pure (E)-1,2-diphenyl-1-propenyltitanocene
    PhC⋮CPh与甲基丙二烯和钛茂衍生物的反应是多机理的。在使用Me 3 Al或Me 2 AlCl与Cl 2 TiCp 2或MeTiCp 2 Cl的1:1混合物的情况下,反应仅通过甲基钛化进行,这需要通过甲基铝烷来促进,但在Ti和Al中都是化学计量的。甲基钛化的产物是≥98%的立体异构纯(E)-1,2-二苯基-1-丙烯基钛茂氯化物(10),与甲基丙氨酸络合,从中可以得到10的纯物质。如果Me 3 Al和Cl 2 TiCp 2的比例为2:1由于使用了不同的反应参数,因此反应过程会有所不同,并且在很大程度上取决于几个反应参数。为了观察已知的Tebbe试剂(4)的形成及其与PhC⋮CPh的反应生成钛环丁烯5的过程,有必要将Me 3 Al和Cl 2 TiCp 2以2:1的比例预混合几天并运行在碱例如DMAP的存在下进行反应。如果未添加碱,则在将Me 3 Al和Cl 2 TiCp 2转化为4之前,会观
  • Decarbonylative Methylation of Aromatic Esters by a Nickel Catalyst
    作者:Toshimasa Okita、Kei Muto、Junichiro Yamaguchi
    DOI:10.1021/acs.orglett.8b01233
    日期:2018.5.18
    A Ni-catalyzed decarbonylative methylation of aromatic esters was achieved using methylaluminums as methylating agents. Dimethylaluminum chlorides uniquely worked as the methyl source. Because of the Lewis acidity of aluminum reagents, less reactive alkyl esters could also undergo the present methylation. By controlling the Lewis acidity of aluminum reagents, a chemoselective decarbonylative cross-coupling
    使用甲基铝作为甲基化剂,可以实现镍催化的芳香族酯的脱羰甲基化。氯化二甲基铝独特地用作甲基源。由于铝试剂的路易斯酸度,反应性较低的烷基酯也可能会发生本甲基化。通过控制铝试剂的路易斯酸度,烷基酯和苯基酯之间的化学选择性脱羰交联是成功的。
  • Lewis Acid-Promoted Coupling Reactions of Acid Chlorides with Organoaluminum and Organozinc Reagents
    作者:Mitsuhiro Arisawa、Yasuhiro Torisawa、Michiaki Kawahara、Masamichi Yamanaka、Atsushi Nishida、Masako Nakagawa
    DOI:10.1021/jo970244a
    日期:1997.6.1
    An efficient synthesis of alpha,beta-unsaturated ketones by the reaction of acid chlorides with trialkylaluminum (1/3 mole equiv) in the presence of AlCl(3) (1 mol equiv) is described. Dialkylzincs were also useful and are easier to prepare than trialkylaluminum. Reaction of RCOCl with R'AlCl(2) or R'(2)AlCl gave R'COR, without AlCl(3), in high yield.
    描述了在AlCl(3)(1摩尔当量)存在下,酰氯与三烷基铝(1/3摩尔当量)的反应,可有效合成α,β-不饱和酮。二烷基锌也是有用的,并且比三烷基铝更容易制备。RCOCl与R'AlCl(2)或R'(2)AlCl的反应以高收率得到了不含AlCl(3)的R'COR。
