  摘要：

  我们合成了 [（二膦）Cr(CO)4] 类型的配合物（二膦 = Ph2PN(iPr)PPh2、Ar2PN(Me)PAr2 或 Ar2PCH2PAr2（Ar = 2-C6H4(MeO)））。在固态下，这些配合物显示出紧密的膦咬合角，范围在 67.82(4)° 至 71.52(5)° 之间，N,N-双（二芳基膦）胺配体中的氮原子几乎呈平面（sp2）几何形状。所有配合物都很容易被电化学或化学氧化成相应的 Cr(I) 物。在 Ar = 2-MeO-C6H4 的衍生物中，没有证据表明垂醚基团在 Cr(0) 或 Cr(I) 物质中配位。用 [NO]BF4 处理[(二膦)Cr(CO)4] 复合物可得到 [(二膦)Cr(NO)(CO)3]BF4。胺氧化物无法通过去除 CO 配体来生成低聚活性物种，但三乙基铝可以有效地发挥这一作用，并且可以生产出活性催化剂。使用弱配位阴离子似乎是实现低聚催化的关键。

  The present invention relates to an in-line method for generating comonomer, from monomer, such as ethylene. The comonomer generated is directly transported, without isolation or storage, to a polyethylene polymerization reactor. The in-line method includes the steps of providing an in-line comonomer synthesis reactor and a downstream gas/liquid phase separator prior to the polymerization reactor; feeding ethylene monomer and a catalyst in a solvent and/or diluent to the comonomer synthesis reactor; reacting the ethylene monomer and the catalyst in solvent and/or diluent under reaction conditions to produce an effluent stream including ethylene monomer and comonomer; passing the effluent stream from the comonomer synthesis reactor to the downstream gas/liquid phase separator to separate a gas stream from a bottom stream, wherein the gas stream is a mixture of ethylene monomer and comonomer; and passing the gas stream to the polymerization reactor to provide the necessary comonomer input,
