New methodology for radical aromaticsubstitution has been developed involving the addition of electron-deficient radicals to unprotected pyrroles and indole. This non-oxidative process is presumed to be occurring via atom-transfer addition of suitable organoiodides and bromides with subsequent non-radical elimination of HI or HBr, respectively. The process also occurs under stannane-free conditions
