    摘要:
    制备了五种取代的环戊二烯基三甲氧基钛络合物RCpTi(OMe)3(R = Me(2b),i Pr(2c),Me 3 Si(2d),烯丙基(2e),PhCH 2(2f))。通过使RCpTi(OMe)3与BF 3 OMe 2反应,六个RCpTiF 2(OMe)(R = H(3a),Me(3b),i Pr(3c),Me 3 Si(3d),烯丙基(3e), PhCH 2(3楼))。当用甲基铝氧烷(MAO)活化时,苯乙烯溶液聚合中RCpTiF 2(OMe)体系的活性低于RCpTi(OMe)3体系,但RCpTiF 2(OMe)制备的聚合物具有更高的Mw和熔点比RCpTi(OMe)3高。两种体系均产生具有相似间同规整度的聚合物,其间规度为92.4-97.6%。在Cp-配体中引入取代基可提高聚合物的熔点,同时降低RCpTi(OMe)3 / MAO和RCpTiF 2(OMe)/ MAO系统的催化活性,其中活性顺序为RCp

    Synthesis, characterization and cytotoxic activity on breast cancer cells of new half-titanocene derivatives
    摘要:
    A series of novel titanocene-complexes has been prepared and evaluated for their growth regulatory effects in MCF7 and SkBr3 breast cancer cells. The capability of some of these compound to elicit relevant repressive effects on cancer cell growth could be taken into account towards novel pharmacological approaches in cancer therapy.

  • Syntheses, structures and reactions of some new benzyl-substituted cyclopentadienyl titanium complexes
    作者:Yanlong Qian、Jiling Huang、Jimin Yang、Albert S.C. Chan、Weichun Chen、Xiaoping Chen、Li Guisheng、Xianglin Jin、Qingchuan Yang

    benzyl-substituted cyclopentadienyl titanium complex 26 may be spontaneously converted into metallocyclic complex 19. The position of the MeO group on the benzene ring is the key factor to the cyclization. In the case of meta- and para-MeO benzyl-substituted titanium complexes 23 and 25, there was no possibility to form a titanoxacycle complex, such as 19, because the MeO group is too far from titanium. A probable
    已经合成了二十八个新的苄基取代的环戊二烯配合物。其中,通过X射线分析研究了五个典型的分子结构。发现在制备含邻-MeO的苄基取代的络合物时,当苄基碳原子上的两个取代基都为Et或更大的基团时,总是形成氧环络合物。卤化物的存在促进了环化反应。卤化物对于环化的活性顺序为:LiI-NaI> LiBr-Br 2 > NaBr-KI> KBr> I 2。高温有利于环化。在80°C下,正常的邻-MeO苄基取代的环戊二烯络合物26可以自发地转化成属环配合物19。MeO基团在苯环上的位置是环化的关键因素。在间-和对-MeO苄基取代的配合物23和25的情况下,由于MeO基团距离太远,因此不可能形成氧杂环丙烷配合物,例如19。提出了一种可能的涉及四元过渡态的机制。
  • Synthesis of hetero-bimetallic metallocene complexes and their catalytic activities for ethylene polymerization
    作者:J Huang
    DOI:10.1016/s1381-1169(02)00361-8
    日期:2002.10.24
    Five new hetero-bimetallic metallocene complexes were synthesized by the reaction of RCpTiCl3 and a Si-bridged zirconocene complex in refluxing toluene. They were all well characterized. These complexes activated with methylaluminoxane (MAO) are highly active catalysts for the polymerization of ethylene. The molecular weight (M-w = 28,957-124,089) and the molecular weight distribution (MWD = 2.04-3.01) of the polymer generated from the bimetallic catalytic system were higher than that obtained by CP2ZrCl2.

  • Synthesis of double silylene-bridged binuclear titanium complexes and their use as catalysts for ethylene polymerization
    作者:Sheng Xu、Zuo-Feng Feng、Ji-Ling Huang

    日期:2006.5
    Five new double silylene-bridged binuclear titanium complexes were synthesized by the reaction of RCpTiCl3 and Li-2[mu,mu-(SiMe2)(2) (C5H3)(2)] in toluene. They were all well characterized. These complexes activated with methylaluminoxane (MAO) are highly active catalysts (2.33 x 10(5) g PE/mol Cat h) for the polymerization of ethylene even at low Al/Ti (Al/Ti = 300). The molecular weight distribution of the polymer indicates broad or bimodal (MWD = 26.76) distribution. (c) 2006 Elsevier B.V. All rights reserved.
