Electron donor-acceptor (EDA) complexes provide a means to initiate radical reactions under visible light irradiation using substrates that do not absorb visible light individually. Catalytic approaches to complex formation are vital for advancing this synthetic strategy as it decouples the complexation and photogeneration of radicals from substrate functionalization, a limitation inherent to stoichiometric approaches that restricts structural diversity. This Synopsis highlights recent developments in EDA complex photochemistry in which either the donor or acceptor are employed catalytically.
电子给体-受体（EDA）配合物提供了一种在可见光照射下引发自由基反应的方法，使用的底物单独不能吸收可见光。对于推进这种合成策略，形成配合物的催化方法至关重要，因为它将自由基的配合物和光生成与底物功能化解耦，这是计量方法固有的限制结构多样性的限制。这篇综述重点介绍了 EDA 配合物光化学中最近的进展，其中要么是供体，要么是受体被催化使用。
