A new catalytic amination of aromatic olefins with anilines is presented. In a domino reaction, substituted quinoline derivatives are obtained in the presence of cationic rhodium complexes, such as [Rh(cod)2]BF4, and PPh3. Ethylbenzene is formed as a by-product in this new oxidative reaction. The first transition metal catalyzed anti-Markovnikov hydroamination of styrene with anilines occurs as a side
提出了一种新的苯胺催化芳香族烯烃的胺化方法。在多米诺反应中,在阳离子铑配合物如[Rh(cod)2] BF4和PPh3的存在下获得取代的喹啉衍生物。乙苯是这种新的氧化反应中的副产物。苯乙烯与苯胺的第一过渡金属催化的反马氏化学加氢胺化反应为副反应。机理研究强烈支持苯乙烯的区域选择性氧化胺化作为关键反应步骤。
