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
本文提出了一种由芳基卤化物(主要是芳基溴化物)制备芳香族锡烷的可见光介导策略。该反应在无金属和添加剂的条件下进行,并表现出广泛的底物范围。所得产物已用于通过 Stille 交叉偶联反应形成 C-C 键。机理研究证明了芳基自由基和三甲基甲锡烷基自由基在 Ar-Sn 键形成中的关键作用。
