  摘要：

  The compounds, 2,6-bis(3,5-dimethylpyrazol-1-ylmethyl)pyridine (MeNNN) (L1) and 2,6-bis(3,5-ditertbutylpyrazol-1-ylmethyl)pyridine (tBuNNN) (L2), react with either [Pd(NCMe)(2)Cl-2] or [Pd(COD)ClMe] to form the mononuclear palladium complexes [Pd(MeNNN)Cl-2] (1), [Pd(MeNNN)ClMe] (2), [Pd((tBu)(N) over cap(N) over capN)Cl-2](3) and [Pd((tBu)(N) over cap(N) over capN)ClMe] (4). Reactions of 1, 2 and 4 with the halide abstractor, NaBAr4 (Ar = 3,5-(CF3)(2)C6H3), led to the formation of stable tridentate cationic species [Pd((Me)(N) over cap(N) over capN)Cl](+)(5), [Pd((Me)(N) over cap(N) over capN)Me](+) (6) and [Pd((tBu)(N) over cap(N) over capN)Cl](+) (7) respectively. The analogous carbonyl linker cationic species [Pd{(3,5-Me(2)pz-CO)(2)py}Cl](+) (9) and [Pd{(3,5-(t)Bu(2)pz-CO)(2-py)}Cl](+) (10), prepared by halide abstraction of the neutral complexes [Pd{(3,5-Me(2)pz-CO)(2)py}Cl-2] and [Pd{(3,5-(t)Bu(2)pz-CO)(2)-py}Cl-2] by NaBAr4, were however less stable with t(1/2) of 14 and 2 days respectively. Attempts to crystallize 1 and 3 from the mother liquor resulted in the isolation of the salts [Pd((Me)(N) over cap(N) over capN)Cl](2)[Pd2Cl6] (11) and [Pd((tBu)(N) over cap(N) over capN)Cl](2)[Pd2Cl6] (12). Although when complexes 1-4 were reacted with modified methylaluminoxane (MMAO) or NaBAr4, no active catalysts for ethylene oligomerization or polymerization were formed, activation with silver triflate (AgOTf) produced active catalysts that oligomerized and polymerized phenylacetylene to a mixture of cis-transoidal and trans-cisoidal polyphenylacetylene.

  摘要：

  具有2，6-吡啶二羰基连接基，{RR'pz（CO）} 2 py，R = R'=  t Bu（L1）的一系列吡唑基化合物；R = R'= Me（L2）; R = R'= H（L3）中，R = H，R'=我（L4）已经从2,6- pyridinedicarbonyl酰氯与适当的吡唑和弱碱的反应来制备。配体L1 – L3与Pd（NCMe）2 Cl 2反应形成单核络合物，而与L4的反应产生难以处理的产物。配合物1和2在用甲基铝氧烷（MAO）活化后，测试了它们对乙烯聚合的催化活性。用MAO原位形成活性聚合催化​​剂，该催化剂催化乙烯聚合成高密度线性聚乙烯。报告了助催化剂浓度和温度的影响。助催化剂与催化剂的最佳比例为3000：1，且由于催化剂失活，催化剂活性在40°C以上下降。
