fragmentations take place, affording anthraquinone, and reactive oxygen species. This mechanism explains the often observed decomposition of endoperoxides during work‐up. Finally, an acid‐catalyzed cleavage has been observed under release of hydrogen peroxide. The results should be interesting for the mechanistic understanding of peroxide decomposition and the endoperoxides might serve as mild sources
蒽内过
氧化物的分解已在各种条件下进行了研究。通过自由基
中间体进行热解,并根据取代方式提供
蒽和重排产物。有趣的是,不仅O-O,而且C-O键均可以均裂。在碱性条件下会发生碎裂,得到
蒽醌和活性
氧。该机制解释了在后处理过程中经常观察到的内过
氧化物的分解。最后,在
过氧化氢的释放下观察到酸催化的裂解。该结果对于过
氧化物分解的机理理解应该是有趣的,并且内过
氧化物可以作为未来应用中活性
氧物种的温和来源。版权所有©2016 John Wiley&Sons,Ltd.
