or chloride or their substituted analogs yields an acridine containing a shorter perfluoroalkyl group at the 9 position and devoid of the methyl group of the Grignard substrate. Interestingly, no acridine is produced in an attempted reaction with aryl magnesium bromide without the ortho methyl group. With 2-fluoro-6-methylphenylmagnesium bromide the methyl group is eliminated and the fluorine is retained
摘要 用 2-甲苯基溴化镁或氯化镁或其取代的类似物处理 2-(全氟烷基)苯胺会产生在 9 位含有较短全氟烷基且不含格氏底物甲基的吖啶。有趣的是,在尝试与没有邻甲基的芳基溴化镁反应时没有产生吖啶。使用 2-氟-6-甲基苯基溴化镁,甲基被消除,氟保留在吖啶产物中。机理研究的结果强烈表明,在空气氧化和水处理过程中中间产物的水解过程中,甲基的损失以甲醇的形式发生。
