The Front Cover shows the pathways for catechol oxidation (foreground) by the copper complexes of cyclen‐containing derivatives of cyclotriphosphazene (background) in aqueous media. Despite the mononuclear nature of the cyclen ligand, the reaction follows a dinuclear pathway determined by means of a “mechanistic Job plot” to reveal the stoichiometry of the transition state by monitoring the reaction rate. The dinuclear transition states imitate “The Creation” by Michelangelo to add some artistic flavor to the chemistry described herein. More information can be found in the Full Paper by Y. Ye, A. Angerhofer, Y. Zhao, L.‐J. Ming et al. For more on the story behind the cover research, see the Cover Profile.

封面：水性介质中环链连接的环三磷腈配体的多铜（II）配合物的催化合作性，核性和O2 / H2O2特异性（Eur。J. Inorg。Chem。42/2017）

封面显示了水性介质中含环三磷腈的环己酮衍生物的铜配合物（背景）引起的邻苯二酚氧化（前景）的途径。尽管周期素配体具有单核性质，但反应仍遵循通过“机械工作图”确定的双核途径，以通过监测反应速率来揭示过渡态的化学计量。双核过渡态模仿了米开朗基罗（Michelangelo）的“创作”（The Creation），为本文所述的化学添加了一些艺术气息。可以在Y. Ye，A.Angerhofer，Y.Zhao，L.J.的全文中找到更多信息。Ming等。有关封面研究背后的故事的更多信息，请参见封面资料。
