A direct oxidative C−H amidation of heteroarenes with sulfonamides via nitrogen‐centered radicals has been achieved. Nitrogen‐centered radicals are directly generated from oxidative cleavage of N−H bonds under visible‐light photoredox catalysis. Sulfonamides, which are easily accessed, are used as tunable nitrogen sources and bleach (aqueous NaClO solution) is used as the oxidant. A variety of heteroarenes,...
