Iron‐Photocatalyzed C(sp3)–H Phosphonylation of Alkanes
Angewandte Chemie, EarlyView.Alkyl phosphonates are valuable motifs that can be prepared by phosphonylations of various common functional groups. However, direct phosphonylations of C(sp3)–H bonds are limited to activated positions. Herein, we report an iron‐photocatalyzed phosphonylation of unactivated C(sp3)–H bonds using a novel phosphite radical trap, which is equipped with an
