Application of Iodine and Iodide in Photocatalysis Organic Synthesis

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.
