  By using iPr2Im as a Lewis base ligand, β-H elimination reactions of propylene polymerization were suppressed at −30 °C. Polypropylene and its block copolymers with ethylene possessing ultra-high molecular weights (Mn > 1,000,000 g/mol) were successfully obtained in high TOFs (PP > 104 mol molSc−1 h−1). DFT calculations suggested that the delocalized electrons in the strongly conjugated system of iPr2Im

  通过使用i Pr 2 Im 作为路易斯碱配体，丙烯聚合的β-H消除反应在-30°C被抑制。 在高TOF（PP > 10 4  mol molSc -1 h -1）中成功获得了具有超高分子量（M n > 1,000,000 g/mol）的聚丙烯及其与乙烯的嵌段共聚物。DFT 计算表明，i Pr 2 Im的强共轭体系中的离域电子可以显着降低活性位点的正电性。这种方法为调节活性位点的电子特性提供了一种方便的策略。

• Alkyl-substituted indenyl titanium precursors for syndiospecific ziegler-natta polymerization of styrene

  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.
