The reaction of iminium triflates 2 and 7 with various aromatic amines were investigated. The 2-Rf-substituted quinolines 3 and 8 were prepared in excellent yields by the reaction of 2 and 7, respectively, with substituted anilines. The reactions of 2 and 7 with diarylamines proceeds, suprisingly, to afford the corresponding 3-Rf-substituted cinnamaldehydes 4 and 9.
研究了亚胺三氟甲磺酸酯 2 和 7 与各种芳香胺的反应。2-Rf 取代的喹啉 3 和 8 分别通过 2 和 7 与取代苯胺的反应以极好的收率制备。令人惊讶的是,2 和 7 与二芳胺的反应进行,得到相应的 3-Rf 取代的肉桂醛 4 和 9。
