Quinoline, isoquinoline, quinaldine, phthalazine, and quinoxaline are all found to react smoothly with perfluoroalkyllithiums in the presence of BF3·OEt2, giving the corresponding perfluoroalkyl addition and/or substitution products in good yields. Perfluoroalkylation occurs at the carbon atom next to the nitrogen.
喹啉、异喹啉、喹啉啶、邻苯二氮杂烯和喹噁啉在 BF3·OEt2 存在下与全氟烷基锂发生平稳反应,生成相应的全氟烷基加成和/或取代产物,并且产率良好。全氟烷基化发生在靠近氮原子的碳原子上。
