2-(全氟乙基)苯胺及其较高的全氟烷基类似物与在邻位被甲基或乙基取代的芳基溴化镁的反应提供了在9位含较短全氟烷基且没有甲基或乙基的a啶格氏试剂。产率在46-93%的范围内。先前已经在文献中假定了取代的氮杂邻二甲苯的中间体用于相关的转化,但是从未分离出该中间体。作为这项工作的一部分,不稳定产品E - 27首次分离(在23°C下半衰期为6h),并通过红外光谱,电子冲击质谱,快速原子轰击质谱和1 H NMR进行表征。还获得了关于在反应过程中以醇的形式除去格氏试剂的邻烷基的实验证据。

Zwitterionic compounds having a group 13 anionic end connected to a group 15 cationic end via a fluorinated aryl group are disclosed herein as being cocatalysts for olefin polymerization catalysts, in particular late transition metal diimine catalysts. The cationic end of the cocatalyst is the portion of the compound that activates the catalyst.

been isolated. As part of this work, the labile product E-27 (half-life of 6 h at 23°C) was isolated for the first time and characterized by infrared spectroscopy, electronimpactmassspectrometry, fastatombombardmentmassspectrometry, and 1H NMR. Experimental evidence was also obtained regarding the elimination of the ortho-alkyl group of the Grignard reagent during the course of the reaction as
