    摘要:
    描述了多种苯甲酰胺钛的合成和反应性。在Et 2 O中向二氯化物L 2 TiCl 2(L = PhC(NSiMe 3)2)中添加0.5当量的Me 2 Mg可以得到高产率的氯烷基衍生物L 2 Ti(Me)Cl。向二氯化物中加入2当量的PhCH 2 MgCl可以中等产率获得热敏L 2 Ti(CH 2 Ph)2。同样地,添加1当量的Me 2 Mg导致干净地形成二甲基L 2 TiMe 2。与二甲基发生反应叔丁胺在回流的苯中形成五配位的亚氨基L 2 TiNCMe 3,为此提供了晶体学数据。在C丙酮酰亚胺进行反应6 d 6,以形成桥接氧代衍生物大号2的Ti(μ-O)2 TIL [η 1 -NC(PH)N(森达3)2 ]。用四氢呋喃(THF)中的1%Na / Hg汞齐过夜还原二氯化物,形成Ti(III)衍生物L 2 TiCl(THF),从己烷中以中等收率结晶。进行类似的甲苯还原反应,得到无碱的氯化钛Ti(III)L

    Reactivity of group 4 benzamidinate complexes towards mono- and bis-substituted silanes and 1,5-hexadiene
    摘要:
    Zirconium and titanium bis(benzamidinate) dimethyl complexes were found to be active catalytic precursors for the oligomerization of mono- and bis-substituted silanes. The activation of such complexes, by an excess of MAO or by an equimolar amount of B(C6F5)(3), increases the catalytic activity of the complexes and the molecular weight of the obtained oligosilanes. The maximum polymerization index that was accomplished (n = 90) is by far the largest obtained with other organometallic complexes. In addition, the activated benzamidinate catalysts were also found to be active for the polymerization of 1,5-hexadiene producing poly(methyl-1,3-cyclopentane). For the latter, the results obtained with C-2-symmetry bis(benzamidinate) dimethyl complexes were compared with a chiral complex bearing a myrtanyl group at the benzamidinate ligand.

At high pressure, complex 10 produces elastomeric polypropylene.

  • Elucidation of Substituent Effects in the Polymerization of Propylene Promoted by Titanium Amidinates
    作者:Sinai Aharonovich、Mark Botoshansky、Yael S. Balazs、Moris S. Eisen

    日期:2012.4.23
    In polymerization reactions, the molecular weight of the polymer depends on the rates of monomer insertion, chain termination, and chain transfer. Here we do present studies indicating why chelating octahedral benzamidinate group IV complexes, which promote the polymerization of propylene with MAO, exhibit a linear free energy relationship with the steric Taft parameter. We correlate that this relationship is encountered with the para substituent of the aromatic ring, far away from the active catalytic site. A number of known events are put together to shed light on the effect of the ancillary ligands in the catalytic polymerization, and a new plausible mechanism for the process is presented.
