最近报道了酸化双环氮杂芳烃与烯烃的分子间脱芳环加成反应。我们在这里报告的关键作用的酸在脱芳环加成喹啉烯烃。实验和理论结果表明，喹啉质子化的关键作用不是促进能量转移，而是提高喹啉三重态对烯烃的反应活性。
The intermolecular dearomative cycloaddition of acidified bicyclic azaarenes with olefins was recently reported. We report here the crucial role of the acid in the dearomative photocycloaddition of quinolines to olefins. Experimental and theoretical results show that the key role of the protonation of quinolines is not to promote the energy transfer but to enhance the reactivity of the triplet state of quinolines toward olefins.
