    摘要: This description addresses fluorinated amine compounds meeting the general formula R′iArF—ER2, where ArF is a fluoroaryl group, E is nitrogen or phosphorous, each R is independently a C1-C20 hydrocarbyl group; or the two Rs may connect to form an unsubstituted or substituted C2-C20 cycloaliphatic group, R′ is a C1-C20 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].
