    摘要:
    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。

    摘要:
    一系列对称和不对称的N,N-bis(diarylphosphino)胺(‘PNP’)配体(Ar2PN(R)PNAr′2: R = Me, Ar2 = o-甲氧基苯基, Ar′2 = 苯, 1; R = Me, Ar2 = o-甲苯基, Ar′2 = 苯, 2; R = Me, Ar2 = 苯(o-乙基), Ar′2 = 苯, 3; R = Me, Ar2 = Ar′2 = o-甲氧基苯基, 4; R = iPr, Ar2 = Ar′2 = 苯, 5)和对称的N,N′-bis(diarylphosphino)二甲基肼(‘PNNP’)配体(Ar2PN(Me)N(Me)PAr2: Ar2 = o-甲苯基, 6; Ar2 = o-甲氧基苯基, 7)已被合成。通过原位与[CrCl3(THF)3]复合后激活的甲基铝氧烷(MAO)进行乙烯/苯乙烯共三聚化和异戊二烯三聚化的催化筛选。PNNP催化体系在异戊二烯三聚化中表现出了显著的活性和选择性的提高,相较于之前报道的PNP体系。在乙烯和苯乙烯共三聚化中,对称和不对称变体的比较导致选择性的转换,不对称催化(o-甲氧基苯基)2PN(Me)PPh2(1)配体体系在共三聚产物分布中独特地引入了两个苯乙烯单体,与熟悉的两个乙烯和一个苯乙烯的ω-取代烯烃有所不同。类型为[(双膦)Cr(CO)4]的配合物8-11也已合成,并报告了其单晶X射线衍射结果。我们提出了这些催化转化的机制,并深入探讨了配体系列对铬环催化中间体的影响。

  • One electron oxidation of chromium N,N-bis(diarylphosphino)amine and bis(diarylphosphino)methane complexes relevant to ethene trimerisation and tetramerisation
    作者:Lucy E. Bowen、Mairi F. Haddow、A. Guy Orpen、Duncan F. Wass
    DOI:10.1039/b700559h
    日期:——
    Complexes of the type [(diphosphine)Cr(CO)4] (diphosphine = Ph2PN(iPr)PPh2, Ar2PN(Me)PAr2 or Ar2PCH2PAr2 (Ar = 2-C6H4(MeO)) have been synthesised. In the solid state, these complexes show tight phosphine bite angles in the range 67.82(4)° to 71.52(5)° and the nitrogen atom in N,N-bis(diarylphophino)amine ligands adopts an almost planar (sp2) geometry. All of the complexes are readily oxidised electrochemically or chemically to corresponding Cr(I) species. There is no evidence for coordination of the pendant ether group in derivatives with Ar = 2-MeO-C6H4 in either Cr(0) or Cr(I) species. Treatment of the [(diphosphine)Cr(CO)4] complexes with [NO]BF4 yields [(diphosphine)Cr(NO)(CO)3]BF4. Removal of CO ligands to generate an oligomerisation-active species is not observed with amine oxides but triethyl aluminium is effective in this role, and active catalysts can be produced. The use of weakly coordinating anions seems crucial in achieving oligomerisation catalysis.
    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。
  • Avoiding MAO: Alternative Activation Methods in Selective Ethylene Oligomerization

    oligomerization of ethylene with catalyst productivities of up to 25010 g gCr–1 h–1 are observed. Selectivity to 1-hexene or 1-octene is a function of ligand structure in an identical fashion to the MAO-activated system. A novel Cr(II) species, [Cr(Ar2PN(Me)PAr2)2][Al(OC4F9)4]2 (5), was isolated from the catalytic mixture. Compound 5 alone does not oligomerize ethylene, but reaction with MAO yields a highly active
