  Copper(II) Ethylene Polymerization Catalysts: Do They Really Exist?

  摘要：

  The reactions of two types of copper(II) ethylene polymerization catalysts, [(sal)CuCl](2) (sal = 2-{C(H)=N(2,6-Pr-i(2)-C6H3)}-4,6-Bu-t(2)-phenoxide) and (alpha-diimine)CuCl2 (alpha-diimine = [(2,6-Pr-i(2)-C6H3)-N=C(Me)](2)). with methylaluminoxane (MAO) and trimethylaluminum (TMA) have been investigated. In both examples, facile and irreversible ligand (L) transfer from copper to TMA present in MAO was observed, resulting in formation of the corresponding (sal)AlMe2 and (imino-amido)AlMe2 complexes. The (imino-amido)AlMe2 complex is formed by alpha-diimine ligand transfer to aluminum followed by alkylation of one imino moiety in the ligand backbone. Both aluminum complexes were active catalysts for ethylene polymerization with activities similar to their Cu(II) precursors. Simple addition of a neutral salicylaldimine or alpha-diimine ligand to MAO in the absence of any copper species resulted in the formation of the corresponding LAlMe2 complexes, which are again active for ethylene polymerization. These results indicate that ethylene polymerization does not occur by a migratory insertion mechanism at the copper center, but is the result of ligand transfer to aluminum, and it is the resulting LAlMe2/LAlMe+-complexes that are likely the active species.

  predictable in their behavior with aromatic-substituted RDAB ligands. Depending on the exact species and ratios used, coordinated adducts can be formed and identified, or inserted/rearranged products similar to the aluminum reactions can be obtained. Quite interestingly, cation/anion pairs can also be formed in which GaCl3 or MeGaCl2 act as a chloride acceptors. This behavior was unique and substantially

  在本报告中，我们研究了Me x MCl 3– x（x = 0–3，M = Al，Ga）与各种芳香族和烷基取代的1,4-二氮杂-1,3-丁二烯R DAB配体的相互作用（或α-二亚胺配体）以形成溶液和固态的多种结构。结合其他先前报道的结构，可以推断出这些物种的某些总体反应趋势，尽管仍然存在一些无法解释的反应模式。甲基化的铝物质与芳族取代的R DAB配体反应，提供最终产物，该最终产物是由C═N插入Al–CH 3组随后发生重排反应。在R DAB配体的主链上添加甲基不足以阻止插入和重排过程的发生。在具有较大的DiPP DAB配体的MeAlCl 2的情况下，可以从单加合物通过插入/重排的最终产物进行光谱跟踪反应。然而，甲基化的Ga物种与芳族取代的R DAB配体的行为很难预测。取决于所使用的确切种类和比例，可以形成和鉴定配位的加合物，或者可以获得类似于铝反应的插入/重排产物。非常有趣的是，也可以在其中形
