transition-metal-free photochemical method featuring excellent functional group tolerance, mild reaction conditions and short reaction times has been discovered and developed for the synthesis of (hetero)aryl trimethylstannanes from (hetero)aryl halides.
preparation of aromatic stannanes from arylhalides (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
