visible‐light‐promoted, tin/boron‐free intermolecular [3+2] atom‐transfer radical cyclization reaction was developed by using iridium polyphenylpridinyl complex as the sensitizer (see scheme). 2‐(Iodomethyl)cyclopropane‐1,1‐dicarboxylate reacted with various alkenes and alkynes to form cyclopentane and cyclopentene derivatives.
