Selectively free: A highly efficient and selective iron-catalyzed oxidative radical cross-coupling/cyclization to prepare dihydrobenzofurans under mild conditions had been established. Phenols and olefins are directly utilized as clean nucleophiles. Mechanistic investigations revealed that the reaction proceeds through a radical pathway, and the high selectivity is due to the Lewis acid.
