  Fifty-three bis(phosphines) were evaluated as ligands for chromium-catalyzed ethylene tetramerization in a high-throughput reactor. Selected ligands previously reported in the literature gave high activities with expected selectivities when evaluated under our reactor conditions. While the majority of ligands evaluated gave low activity catalysts that produced mostly high-density polyethylene (HDPE)

  在高通量反应器中评估了53种双（膦）作为铬催化的乙烯四聚的配体。在我们的反应器条件下进行评估时，先前在文献中报道的选定配体具有很高的活性和预期的选择性。尽管大多数评估的配体都提供了低活性催化剂，这些催化剂大多生产高密度聚乙烯（HDPE），但烷基膦却被意外地鉴定为有前途的配体类别。尤其是，MeDuPhos配体产生了一种活性催化剂，该催化剂产生了81.8 wt％的α-烯烃（50.0 wt％的1-辛烯，31.8 wt％的1-己烯）和3.5 wt％的HDPE，接近了当时的选择性-art我-Pr-PNP配体。

  Chromium complexes with bis(phospholane) ligands were synthesized and evaluated for ethylene tetramerization in a high-throughput reactor. Three ligand parameters—the phospholane substituent, the ligand backbone, and the type of phosphine (cyclic vs acyclic)—were investigated. The size of the phospholane substituent was found to impact the selectivity of the resulting catalysts, with smaller substituents

  合成了具有双（膦）配体的铬配合物，并在高通量反应器中评估了乙烯的四聚作用。研究了三个配体参数-膦酸酯取代基，配体主链和膦的类型（环状与非环状）。发现磷烷取代基的大小影响所得催化剂的选择性，其中较小的取代基导致较大比例的1-辛烯的产生。将配体主链从1,2-亚苯基更改为乙烯不会影响催化，但是使用无环膦代替环状膦烷会对催化活性产生不利影响。在300 mL帕尔反应器中，在70°C和700 psi的乙烯压力下，评估了选定的磷杂环戊二烯-铬配合物，乙烯低聚性能与在较小的高通量反应器中观察到的一致。甲基氯化铬3（THF）（MeDuPhos = 1,2-双（2,5-二甲基phospholano）苯; THF =四氢呋喃），得到活性和选择性为1-辛烯（54.8重量％）类似于状态的最先进的我- PrPNP-CrCl 3（THF）（64.0 wt％）（PNP =双（二苯基膦基）胺），而EtDuPhos-CrCl
