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 chlorineatom transfer. A wide variety of carboxamides and sulfonamides were chlorinated at the δ-position by using this method

efficient N-chlorination, and the created cavity favors a six-membered cyclic transitionstate for chlorineatom transfer, boosting the site-selective C(sp3)–H chlorination of amides/sulfonamides in the water. Our mechanistic investigations have disclosed the rate-determining N–Cl activation mode within the cavity for the chlorineatom transfer pathways.
