heteroarylation of amides via C(sp3)–Hbondfunctionalization. Amidyl radicals are directly generated from the amide N–H bonds under mild conditions, which trigger the subsequent 1,5-HAT process. A wide scope of aliphatic amides including carboxamides, sulfonamides, and phosphoramides are readily modified at remoteC(sp3)–H bonds by installing diverse heteroaryl groups. Borne out of pragmatic consideration

general strategy for the remote-site-selective cascade addition/cyclization of unactivatedC(sp3)–H bonds in free alcohols and sulfonamides to build isoquinolinonedione skeletons is developed. The site selectivity occurs predominantly via a 1,5-hydrogen atom transfer (HAT) process, triggered by heteroatom-centred radicals generated directly under silver catalysis. A broad substrate scope and excellent
