摘要：
A novel intramolecular oxidative coupling reaction has been established to prepare benzofuran derivatives via direct C(sp(2))-H functionalization for the formation of C-O bond. This transformation is mediated by I-2/TBHP/NaN3 under metal-free conditions and a catalytic amount of NaN3 plays a crucial role in the reaction. Furthermore, the reaction tolerates a broad substrate scope with average to excellent yields.
