Radical chemistry! A 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.
