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

research interest in drug chemistry and organic synthesis in recent years. Herein, we report a facile access to benzocyclic boronates through photopromoted intramolecular arylborylation of allyl aryldiazonium salts. This simple protocol features a broad scope, allowing the formation of variously functionalized borates bearing dihydrobenzofuran, dihydroindene, benzothiophene, and indoline skeletons under
