  摘要：

  铑（III）络合物的[Cp *的RhCl（dfppe）] BF 4，1，经历快速的分子内逐步在加入质子海绵以产生dehydrofluorinative碳-碳偶联[{η 5，κ P，κ P -C 5我3 [CH 2 C 6 F 4 -2-P（C 6 F 5）CH 2 ] 2 -1,3} RhCl] BF 4。该反应所需的质子海绵的化学计量数量少于化学计量的数量，并且在添加Bu n时也会发生4 NF或在聚合物负载的氟化物存在下。一系列配合物与质子海绵之间反应的NMR研究表明，五甲基环戊二烯基铑（III）膦配合物中分子内脱氢氟化偶联的必要条件。该络合物必须是阳离子的，而膦既可以是螯合配体的一部分，也可以是单齿的，只需要一个五氟苯基取代基即可。在Cp *和C 6 F 5紧密靠近的情况下，反应迅速。化合物的[Cp *的RhCl {（C 6 ˚F 5）2 PC 6 H ^ 4 SME-2}] BF 4，7，和的[Cp

  Fluorinated amine compounds, R'iArF-ER2, where ArF is a fluo-roaryl substituent, E is nitrogen or phosphorous, each R is independently a C1-C20 hydrocarbyl substituent, or the two R's may be connected to form an unsubstituted or substituted C2-C20 cycloaliphatic substituent, R' is a C1-C20 hydrocarbyl or halogenated hydrocarbyl, and i is 0, 1 or 2 are disclosed. These compounds may be protonated and complexed with suitable substantially noncoordinating anions to prepare polymerization catalyst components. When these catalyst components are combined with organometallic catalyst precursors, the catalyst precursor is activated to a catalyst. This catalyst is combined with monomer under olefin polymerization conditions to prepare polymer. High number-average molecular weight polymers at high productivity rates were observed from using metallocene catalysts activated with [N-pentafluorophenyl pyrrolidinium] [tetrakis(pentafluorophenyl) borate].

  本发明公开了氟化胺化合物 R'iArF-ER2，其中 ArF 为氟芳基取代基，E 为氮或磷，每个 R 独立为 C1-C20 碳氢基取代基，或两个 R 连接形成未取代或取代的 C2-C20 环脂族取代基，R'为 C1-C20 碳氢基或卤代碳氢基，i 为 0、1 或 2。这些化合物可以质子化并与适当的基本不配位阴离子络合，制备聚合催化剂组分。当这些催化剂组分与有机金属催化剂前体结合时，催化剂前体被活化成催化剂。催化剂在烯烃聚合条件下与单体结合，制备聚合物。使用[N-五氟苯基吡咯烷][四(五氟苯基)硼酸酯]活化的茂金属催化剂可以观察到高生产率下的高平均分子量聚合物。
