Radical aromatic substitution via atom-transfer addition

Article abstract of DOI:10.1016/S0040-4039(99)00304-4

New methodology for radical aromatic substitution 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.
