  有机金属重排的研究：III。不对称取代的茚基阴离子的反应。初始反应产物的异构化

  摘要：

  非对称的1-取代的茚基阴离子，1-RC 9 H - 6 [I，R = CH 3 ; II，Si（CH 3）3 ]与各种亲电试剂反应，得到在C（1）和C（3）处均被取代的产物。阴离子I在C（3）处主要或唯一地结合了进入基团，得到1-取代的3-甲基茚，而阴离子II在C（1）和C（3）处反应生成异构体的混合物。在一些情况下，初始动力学产物经历异构化为热力学更稳定的产物，并报道了这些反应的动力学参数。根据空间效应和电子效应讨论了阴离子猝灭反应的结果。

• Alkyl-substituted indenyl titanium precursors for syndiospecific ziegler-natta polymerization of styrene
  作者：Thomas E. Ready、James C.W. Chien、Marvin D. Rausch

  A variety of 1- and 3-substituted alkylindenes (R = H, Me, Et, tert-butyl, Me(3)Si) as well as 2-methylindene and 3-(methylthio)indene have been prepared in good yields. The substituted indenes were converted into trimethylsilyl derivatives via reactions of intermediate organolithium complexes with chlorotrimethylsilane. The corresponding titanium complexes, (R-Ind)TiCl3, were synthesized in excellent yield from reactions of the trimethylsilyl derivatives with TiCl4. The titanium complexes were evaluated as styrene polymerization catalysts in toluene solution when activated by methylaluminoxane. Activities increased in the order: Cp < H(4)Ind < Ind < 1-(Me)Ind < 2-(Me)Ind. A steep drop in activity was observed when R = Et, tert-butyl, and Me(3)Si, corresponding to an increase in the steric bulk of the substituent in the catalyst precursor. 1-(MeS)IndTiCl(3) was found to be ineffective as a styrene polymerization catalyst. Syndiospecificities of the titanium complexes were generally very good (65-98%).
• Synthesis and polymerization behavior of various substituted indenyl titanium complexes as catalysts for syndiotactic polystyrene

  Five substituted indenyltrichlorotitanium compounds have been synthesized and characterized by spectroscopic methods and their catalytic behavior for the polymerization of styrene was studied in the presence of methylaluminoxane (MAO) as a cocatalyst. Substituted indenyl ligands include 1,3-dimethyl, 1-methyl, 1-ethyl, 1-isopropyl and 1-(trimethylsilyl)indenyl groups. All five compounds gave extremely pure syndiotactic polystyrene, with conversion rates of at least 95%, and their catalytic properties were compared with the data obtained from the (eta(5)-indenyl)trichlorotitanium-MAO system. The catalytic activity is enhanced by less bulky and better electron-releasing substituents of the indenyl ligand.
