  Synthesis, acidity and 19F NMR characteristics of imidazoles bearing 1-fluorinated substituents with potential application as probes for intracellular pH determination

  摘要：

  A series of 1-substituted imidazoles containing fluorine have been prepared. These compounds were identified as potentially useful probes for intracellular pH determination based on F-19 NMR. Key parameters including pK(a), F-19 NMR chemical shift sensitivity, water solubility and low toxicity were identified and included in the target molecule selection process. The pK(a) and F-19 NMR parameters of the molecules are reported and vends analysed. (C) 1997 Elsevier Science Ltd.

• Copolymerization of ethylene with 1-hexene promoted by novel multi-chelated non-metallocene complexes with imine bridged imidazole ligand
  作者：Lifu Ma、Hongli Wang、Jianjun Yi、Qigu Huang、Kejing Gao、Wantai Yang

  DOI：10.1002/pola.23800

  日期：2010.1.15

  A series of novel bridged multi‐chelated non‐metallocene catalysts is synthesized by the treatment of N,N‐imidazole, N,N‐dimethylimidazole, and N,N‐benzimidazole with n‐BuLi, 2,6‐dimethylaniline, and MCl4 (M = Ti, Zr) in THF. These catalysts are used for copolymerization of ethylene with 1‐hexene after activated by methylaluminoxane (MAO). The effects of polymerization temperature, Al/M molar ratio

  一系列新颖的桥连多螯合非茂金属催化剂是由处理的合成N，N-咪唑，N，N- -dimethylimidazole，和N，N-苯并咪唑与Ñ正丁基锂，2,6-二甲基苯胺，和MCL 4（M ＝ Ti，Zr）在THF中的溶液。这些催化剂被甲基铝氧烷（MAO）活化后，用于乙烯与1-己烯的共聚。详细研究了聚合温度，Al / M摩尔比和单体压力对乙烯共聚行为的影响。这些结果表明，这些催化剂有利于乙烯与1-己烯的共聚，具有高催化活性和高共聚单体掺入率。共聚物的特点是13C NMR，WAXD，GPC和DSC。结果证实，所获得的共聚物具有约33–35的宽分子量分布（MWD）和高达9.2 mol％的1-己烯高掺入量，共聚物的熔融温度取决于共聚物链中1-己烯的掺入量和共聚物链中的1-己烯单元被乙烯单元隔离。乙烯均聚物的MWD范围更广，为42-46。©2009 Wiley Periodicals，Inc.
