Photoinduced C–N Coupling of 6‐Aminouracil With Aryl Iodide: Aryl Iodide as a Source of Aryl Radical

ABSTRACT A photoinduced C─N coupling reaction between 6‐aminouracil and aryl iodides has been developed under visible light using N,N′ ‐bis(2,6‐diisopropylphenyl)‐3,4,9,10‐perylenetetracarboxylic diimide (PDI) as an organic photocatalyst. This metal‐free protocol offers a sustainable and straightforward method for synthesizing of C─N coupled uracil derivatives under mild conditions. The methodology highlights the potential of PDI‐based photoredox catalysis for achieving efficient C─N bond formation via visible‐light‐driven single‐electron transfer processes.
