  通过改良的Combes反应形成喹啉：检查动力学，取代基效应和机制途径

  摘要：

  这是首次报道使用19F NMR光谱监测Combes缩合以监测中间消耗和产物生成速率的Combes缩合反应。发现该反应在二酮和苯胺中都是一级的。发现产物的区域选择性和反应速率受二酮和苯胺上取代基的影响，速率变化多达五倍。关键亚胺和烯胺中间体的消耗速率与喹啉形成速率一致，反映出喹啉的形成速率。一个ρ确定该环化的-0.32。尽管反应常数的符号与限速亲电子芳族取代（EAS）一致，但该值很可能是复合值，这是由于亲核加成和EAS步骤中相反的取代基效应所致。提出了支持这些发现的机制细节和反应途径。版权所有©2008 John Wiley＆Sons，Ltd.

  摘要：

  一系列含有两个位异构的三氟甲基取代烯胺酮配体的新型钛配合物（3a-h和6a-h），[PhNCRCHC(CF3)O]2TiCl2（3a，R = Me；3b，R = n-C5H11；3c，R = i-Pr；3d，R = Cy；3e，R = t-Bu；3f，R = CHCHPh；3g，R = Et；3h，R = n-C11H23）和[PhNC(CF3)CHC(R)O]2TiCl2（6a，R = Ph；6b，R = n-C5H11；6c，R = i-Pr；6d，R = Cy；6e，R = t-Bu；6f，R = CHCHPh；6g，R = CHPh2；6h，R = CF3）已被合成并表征。X射线晶体结构分析表明，配合物3c-e和6c-d在钛中心周围均采取扭曲的八面体几何构型。配合物3c、3d和6c在钛中心周围显示出两个氯原子的顺式构型，而配合物6d显示出两个氯原子的反式构型。特别是，通过NMR和X射线分析在溶液和固态中都确定了配合物3e的构型异构体（顺式和反式）。以改性甲基铝氧烷为共催化剂，所有配合物均对乙烯聚合活性良好，并生成高分子量聚合物。随着β-烯胺酮配体中亚胺基和三氟甲基相对位置的变化，催化剂的聚合行为发生了显著变化。观察到，直接连接到配体中羰基上的取代基对于催化活性和所生成聚合物的性质起着重要作用。

  A series of new titanium complexes bearing two regioisomeric trifluoromethyl-containing enaminoketonato ligands (3a–h and 6a–h), [PhNCRCHC(CF3)O]2TiCl2 (3a, R = Me; 3b, R = n-C5H11; 3c, R = i-Pr; 3d, R = Cy; 3e, R = t-Bu; 3f, R = CHCHPh; 3g, R = Et; 3h, R = n-C11H23) and [PhNC(CF3)CHC(R)O]2TiCl2 (6a, R = Ph; 6b, R = n-C5H11; 6c, R = i-Pr; 6d, R = Cy; 6e, R = t–Bu; 6f, R = CHCHPh; 6g, R = CHPh2; 6h, R = CF3) have been synthesized and characterized. X-ray crystal structures analyses suggest that complexes 3c–e and 6c–d all adopt a distorted octahedral geometry around the titanium center. Complexes 3c, 3d and 6c display a cis-configuration of the two chlorine atoms around the titanium center, while complex 6d shows a trans-configuration of the two chlorine atoms. Especially, the configurational isomers (cis and trans) of complex 3e were identified both in solution and in the solid state by NMR and X-ray analyses. With modified methylaluminoxane as a cocatalyst, all the complexes are active towards ethylene polymerization, and produce high molecular weight polymers. With the variation of the relative position of the imino group and the trifluoromethyl group of the β-enaminoketonato ligands, the polymerization behavior of the catalysts changed remarkably. It is observed that the substituent directly joined to the carbonyl in the ligands plays an important role for both the catalytic activities and the properties of the polymers produced.

  Zirconium complexes with enolatoimine ligands bearing an electron-withdrawing trifluoromethyl group on the alkoxy moiety [κ2-N,O-2,6-R2NC(CH3)C(H)C(O)CF3]2ZrCl2 (2a, R = H; 2b, R = F; 2c, R = CH3; 2d, R = iPr) were prepared. The isopropyl substituents hinder rotation in solution for 2d, and result in a trans-arrangement of the N-donors in the solid state. Catalyst activities are similar for 2a/MAO and 2b/MAO in ethylene polymerization (1.8 × 105 TO h−1 for 2a and 3.3 × 105 TO h−1 for 2b at 25 °C under 1 bar monomer pressure), increasingly bulky alkyl substituents result in strongly decreased polymerization activities (7.1 × 102 TO h−1 for 2c and 5.7 × 102 TO h−1 for 2d at 25 °C). This goes along with an increase in polymer molecular weight (Mw = 8.1 × 103, Mw/Mn = 2.9 for 2a, Mw = 3.8 × 105, Mw/Mn = 2.0 for 2b, Mw = 1.0 × 106, Mw/Mn = 2.8 for 2c), apparently bulky substituents retard chain transfer even more strongly than activation of the precursors and/or chain growth. 2b/MAO affords atactic polypropylene (Mw = 1.4 × 104 g mol−1, Mw/Mn = 2.1) with a small portion of regioirregular structures. The reaction of [Zr(CH2Ph)4] with the ketoenamine 2,6-F2C6H3N(H)CMeCHC(O)CF3 (1b) yielded the dibenzyl complex [(o-F2C6H3NCMeCHC(CF3)O)2Zr(CH2Ph)2] (3b) which was investigated as a catalyst precursor for ethylene homopolymerization in combination with different activators.

  带有烯醇亚胺配体的锆配合物，烷氧基部分上带有吸电子三氟甲基基团 [κ2-N,O-2,6-R2NC(CH3)C(H)C(O)CF3]2ZrCl2 (2a, R = H;制备了2b，R=F；2c，R=CH3；2d，R=iPr)。异丙基取代基在溶液中阻碍旋转 2d，并导致固态 N-供体发生反式排列。乙烯聚合中 2a/MAO 和 2b/MAO 的催化剂活性相似（2a 为 1.8 × 105 TO h−1，2b 为 3.3 × 105 TO h−1，在 25 °C、1 bar 单体压力下），烷基取代基越来越大导致聚合活性大大降低（2c 为 7.1 × 102 TO h−1，2c 为 5.7 × 102 TO h−1） h−1 在 25 °C 下持续 2d）。这伴随着聚合物分子量的增加（2a的Mw = 8.1 × 103，Mw/Mn = 2.9，Mw = 3.8 × 105，2b的Mw/Mn = 2.0，Mw = 1.0 × 106，Mw/Mn = 2.8对于2c)，明显庞大的取代基比前体和/或链的活化更强烈地阻碍链转移 生长。 2b/MAO 提供具有一小部分区域不规则结构的无规聚丙烯（Mw = 1.4 × 104 g mol−1，Mw/Mn = 2.1）。 [Zr(CH2Ph)4] 与酮烯胺 2,6-F2C6H3N(H)CMeCHC(O)CF3 (1b) 反应生成二苄基络合物 [(o-F2C6H3NCMeCHC(CF3)O)2Zr(CH2Ph)2] ( 3b）将其与不同的活化剂结合作为乙烯均聚的催化剂前体进行研究。

  With a new titanium imineenolato complex, ethylene is polymerized in an unprecedented living fashion affording a polymer with a high molecular weight (M-n > 10(5) g mol(-1)) and an extremely narrow distribution (M-w/M-n 1.01) at the time; the living character is also retained even at an elevated temperature of 75 degrees C, and blockcopolymers are accessible.
