近几十年来, 高价碘试剂受到有机合成化学工作者的关注, 并被广泛应用于有机合成反应中. 相较于强氧化性的五价碘试剂, 三价的高价碘试剂呈现出弱氧化性, 更符合绿色、环境友好的特点. 在过去十几年, 可见光诱导光致氧化还原催化反应作为一种强劲的有机合成新方法, 实现了许多重要的化学转化. 同时, 一些三价的碘试剂由于结构稳定、易获得的特点, 也被广泛应用于可见光促进的光化学反应中. 特别是苯并碘氧杂戊环(酮)类的三价碘试剂, 由于其优良的化学反应活性, 可以作为氧化剂、自由基受体、自由基前体和共催化剂, 从而参与到光化学反应中. 另外, 二醋酸碘苯及其衍生物在光催化的反应中也可以经历类似的反应途径. 三价碘试剂表现出的弱氧化性和优良的亲电性主要归结于其结构中含有高度极化的I—X键, 容易发生断裂. 主要总结并讨论了从2016年以来三价碘试剂参与光催化反应的研究进展, 根据不同类型的三价碘试剂参与的光化学反应, 就其反应特点和机理过程进行详细的讨论和陈述; 同时, 针对三价碘试剂将来的应用前景也进行了讨论.

Hypervalent iodine reagents have attracted much attention from organic synthetic chemists. Compared to the strong oxidizing iodine(V) reagents, iodine(III) reagents show a weaker oxidizing ability, which could meet green and environmentally-friendly properties. Over the past decade, visible-light-induced photoredox catalysis has merged as a powerful tool in organic synthetic methodology, and a rapid development was witnessed. It is worth noting that some iodine(III) reagents which are stable and easily available, have been widely utilized in visible light photocatalytic reactions. Particularly, benziodoxol(on)e reagents, due to their excellent activation properties, which can serve as oxidant, radical acceptor, radical precursor and co-catalyst in photocatalytic reactions, allow for many significant chemical transformations. Additionally, phenyliodine(III) diacetate and its derivatives can proceed similar pathway in photocatalytic reactions. These issues attribute to the highly polarized I—X bond of iodine reagents, leads to their oxidizing ability and superior electrophilicity. Herein, some significant advances since in 2016 are summaried and discussed in terms of chemical transformations and mechanisms of different iodine(III) reagents. In addition, the application prospects in the future are also discussed.
