Abstract

AbstractA visible light‐mediated strategy for the preparation of aromatic stannanes from aryl halides (mostly aryl bromides) is presented herein. The reaction proceeds under metal‐ and additive‐free conditions and exhibits a broad substrate scope. The products obtained have been employed in the C−C bond formation via Stille cross‐coupling reactions. Mechanistic investigation evidenced the key role of both aryl radical and trimethylstannyl radical in Ar−Sn bond formation.
