  The series of 2-(1-(2,4-dibenzhydrylnaphthylimino)ethyl)-6-(1-(arylimino)ethyl)pyridine derivatives and their cobalt chlorides (Co1−Co5) were synthesized and fully characterized. The representative complexes Co2 and Co3 were confirmed by single crystal X-ray diffraction analyses, indicating pseudo-square-pyramidal geometry around the cobalt centre. All cobalt complexes, activated with either methylaluminoxane

  all nickel complexes performed with high activities (up to 1.22 × 107 g (PE) mol−1 (Ni) h−1) towards ethylene polymerization; the obtained polyethylene possessed high branching, low molecular weight and narrow polydispersity, suggestive of a single-site active species. The effect of the polymerization parameters, including the nature of the ligands/halides on the catalytic performance is discussed.

  late-transition-metal catalysts often require bulky steric substituents on both sides of the ortho-aryl position to achieve efficient suppression of chain transfer in ethylene polymerization. In this contribution, we demonstrated that α-diimine catalysts based on naphthylamine with only one bulky ortho-aryl substituent also demonstrated excellent capabilities to suppress the chain transfer. Firstly, a class

  通常，基于苯胺的后过渡金属催化剂通常需要在邻芳基位置的两侧具有庞大的空间取代基，以实现乙烯聚合中链转移的有效抑制。在这一贡献中，我们证明了基于萘胺且只有一个庞大的邻芳基取代基的 α-二亚胺催化剂也表现出出色的抑制链转移的能力。首先，合成并表征了一类只有一个邻芳基二苯甲基或邻芳基二苯并环庚基取代基的α-二亚胺镍钯配合物。其次，所制备的萘胺基镍催化剂表现出优异的活性（高达 13.02 × 10 6 g·mol–1 ·h –1 ) 并在乙烯聚合中产生具有非常高分子量 (445.8–854.3 kg/mol) 的轻度支化 (16–40/1000C) 聚乙烯。相比之下，相应的钯催化剂表现出中等活性（水平为 10 4 —10 5 g·mol –1 ·h –1），生成适度支化（47—78/1000C）的聚乙烯，分子量适中（21.6—82.0 kg/摩尔）。此外，钯催化剂还可以共聚合乙烯和丙烯酸甲酯 (MA)，尽管活性较低（水平为

  The newly prepared 8-(2-benzhydrylnaphthylimino)-5,6,7-trihydroquinoline derivatives (L1-L3) individually reacted with (DME) NiBr2 or NiCl2 to form their corresponding nickel bromide complexes (Ni1-Ni3) and nickel chloride complexes (Ni4-Ni6). These nickel complexes were fully characterized by FT-IR spectroscopy and elemental analysis as well as single crystal X-ray analysis. The representative molecular structures of Ni1 and Ni4, confirmed by single crystal X-ray diffraction, revealed a distorted octahedral geometry around nickel atom as the halo-bridged centro-symmetric dimers with formulae as L2Ni2X4 (X = Br, Ni1-Ni3; X = Cl, Ni4-Ni6). All nickel complexes, activated with either modified methylaluminoxane (MMAO) or diethylaluminiumchloride (Et2AlCl), exhibited high activities toward ethylene polymerization, producing branched polyethylene with low molecular weights. The obtained polyethylenes showed tail peaks in the high molecular weight portion according to the GPC curves due to the constrained geometry caused by the bulky 2-benzhydrylnaphthyl-substituted 8-arylimino-5,6,7-trihydroquinoline derivatives.
