A copper-catalyzed radical carbochlorination or carbobromination is reported. Intramolecular cyclization occurred through aryl radicals generated in situ from bench-stable aryl amines with aqueous hydrogen halides as the halogen sources. A variety of (3-halomethyl)-1,2-dihydrobenzofuran derivatives were prepared in up to 92% yield through this one-pot protocol utilizing widely available starting materials
