Intermolecular Visible-Light Photoredox Atom-Transfer Radical [3+2]-Cyclization of 2-(Iodomethyl)cyclopropane-1,1-dicarboxylate with Alkenes and Alkynes

Intermolecular Visible-Light Photoredox Atom-Transfer Radical [3+2]-Cyclization of 2-(Iodomethyl)cyclopropane-1,1-dicarboxylate with Alkenes and Alkynes

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...

Zusammenfassung: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.
