碘及碘化物在光催化有机合成中的应用

Application of Iodine and Iodide in Photocatalysis Organic Synthesis

光氧化还原已成为在温和条件下高选择性实现各种化学转化的通用工具,然而传统的光催化严重依赖光催化剂,存在价格昂贵和环境污染等问题.碘及碘化物廉价、低毒并具有独特的光反应活性.近年来,它们在光化学合成中的应用引起了人们越来越多的关注.总结了近年来由碘及碘化物介导的光催化反应研究的进展,并对其研究前景进行了展望.

Photoredox catalysis has become a universal tool to catalyze a wide variety of chemical reactions with high selectivity under mild conditions.However,traditional photocatalysis relies heavily on photocatalysts with the problems such as high price and environmental pollution.Because iodine and iodide have the advantages of cheap,non-toxic and unique photoreactivity,their application in photochemical synthesis has attracted more and more attention in recent years.The research progress of photo-redox catalysis reactions mediated by iodine and iodide in recent years is summarized,and their future outlook is also discussed.
