光化学为发现合成有用的转化提供了一个重要的平台。然而，新的氧化光反应的发展已被证明是相对具有挑战性的。在这些反应的设计中，终端氧化剂的身份的重要性一直没有得到充分的重视。基态催化方法中使用的许多最常见的末端氧化剂与光氧化还原反应所特有的单电子氧化状态变化很难兼容，导致难以控制的有害副反应。作为另一种选择，铜(II)盐已成为光化学氧化反应中用途广泛的末端氧化剂，这些反应具有资源丰富、成本低、易于与单电子氧化状态变化相容的特点。本文重点介绍了近年来利用铜(II)氧化与底物的光化学活化或将铜(II)盐同时用作活性发色团和终端氧化剂的反应方法。
Photochemistry provides an important platform for the discovery of synthetically useful transformations. The development of new oxidative photoreactions, however, has proven to be relatively challenging. The importance of the identity of the terminal oxidant has been an underappreciated consideration in the design of these reactions. Many of the most common terminal oxidants used in ground-state catalytic methods are poorly compatible with the one-electron oxidation state changes characteristic of photoredox reactions and result in hard-to-control deleterious side reactions. As an alternative, Cu(II) salts have emerged as versatile terminal oxidants in photochemical oxidation reactions that are terrestrially abundant, cost-effective, and readily compatible with one-electron oxidation state changes. This review highlights recent reaction methods that leverage Cu(II) oxidation in combination with the photochemical activation of substrates or that use Cu(II) salts as both the active chromophore and terminal oxidant.
