Photoinduced C(sp3)-H chlorination of amides with tetrabutyl ammonium chloride

Zhu, Yanshuo,Yu, Wei

supporting information, p. 10228 - 10232 (2021/12/13)

A new protocol was developed for the site-selective C(sp3)-H chlorination of amides with tetrabutyl ammonium chloride as the chlorinating agent. The reaction features a tandem sequence that involves a (diacetoxyiodo)benzene-mediated and chloride anion-involved N-H chlorination followed by photoinitiated chlorine atom transfer. A wide variety of carboxamides and sulfonamides were chlorinated at the δ-position by using this method.
