  and C5NF5. The reactions occur even under mild conditions (T = 0-20 C), either in benzene or without solvent, to give as a rule 4-X-1-(dimethylphosphano)tetrafluorobenzenes (XC6F4PMe2, 1-4) and 4-(dimethylphosphano)tetrafluoropyridine (C5NF4PMe2, 5), respectively, in yields between 75 and 95%. In the case of C6F6, double substitution is also observed, which affords 1,4-bis(dimethylphosphano)tetrafluorobenzene

  The exchange of one fluorine atom in the phosphane (C6F5)Me2P by hydrogen makes a substantial difference in the aggregation motifs of its copper(I) and silver(I) chloride complexes; weak aryl⋅⋅⋅aryl stacking and H⋅⋅⋅Cl interactions are responsible for this structural difference explored in the solid-state (XRD) as well as in solution (VT-DOSY).

  This description addresses fluorinated amine compounds meeting the general formula R′ i ArF-ER 2 , where ArF is a fluoroaryl group, E is nitrogen or phosphorous, each R is independently a C 1 -C 20 hydrocarbyl group, or the two Rs may connect to form an unsubstituted or substituted C 2 -C 20 cycloaliphatic group, R′ is a C 1 -C 20 hydrocarbyl or halogenated hydrocarbyl, and i is 0, 1 or 2. These compounds may be protonated with strong Bronsted acids to form protonated amine compounds that are useful for the preparation of organometallic catalyst-cocatalyst compounds comprising noncoordinating or weakly coordinating anions. The resulting organometallic catalyst-cocatalyst complexes can be effectively used as olefin polymerization catalysts. High number-average molecular weight polymers at high rates of productivity were observed from the use of metallocene catalyst complexes prepared with [N-pentafluorophenyl pyrrolidinium][tetrakis(pentafluorophenyl)borate] of [N-pentafluorophenyl pyrrolidinium][chloride].

  本说明涉及符合通式 R′ 的氟化胺化合物 i ArF-ER 2 其中 ArF 是氟芳基，E 是氮或磷，每个 R 独立地是 C 1 -C 20 烃基，或两个 R 可连接形成未取代或取代的 C 2 -C 20 环脂族基团，R′是一个 C 1 -C 20 烃基或卤代烃基，i 为 0、1 或 2。这些化合物可以用强勃朗斯特酸质子化，形成质子化胺化合物，用于制备包含非配位或弱配位阴离子的有机金属催化剂-催化剂化合物。由此得到的有机金属催化剂-催化剂复合物可有效地用作烯烃聚合催化剂。使用 [N-pentafluorophenyl pyrrolidinium][tetrakis(pentafluorophenyl)borate] of [N-pentafluorophenyl pyrrolidinium][chloride] 制备的茂金属催化剂络合物，可以观察到生产率高的高平均分子量聚合物。

  Fluorinated amine compounds, R′ i ArF-ER 2 , where ArF is a fluoroaryl substituent, E is nitrogen or phosphorous, each R is independently a C 1 -C 20 hydrocarbyl substituent, or the two R's may be connected to form an unsubstituted or substituted C 2 -C 20 cycloaliphatic substituent, R′ is a C 1 -C 20 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].
