Amidoalkylation of Sulfonylheteroarenes with Alkylamides through a Radical Chain Mechanism

Abstract In the presence of a substoichiometric amount of a tert ‐butoxy radical precursor and a base, alkylamides were found to be heteroarylated at their α‐C−H bonds with sulfonylheteroarenes through homolytic aromatic substitution, where a radical chain is operative.
