Compared with well-developed radical aromatic ring migration, heteroatomic radical migration and alkenyl radical migration remain challenging. Herein, a photoinduced remote radical migration reaction based on the aromatic skeleton through tetracoordinate boron species has been developed. In this work, commercially available diboron reagent (B₂pin₂) or alkenyl boron (alkenylBpin) react with o-bromostyrenes as well as their analogues under the mediation of lithium reagents in a single-vessel reaction. This process undergoes an interesting 1,4-, 1,5- or 1,6-remote radical migration via intramolecular circular transition state, which introduces a large array of boron-migrative or alkenyl-migrative compounds. In particular, the 1,6-radical migration reaction has not been reported before. This protocol features readily accessible starting materials, high atom economy, broad substrate scope and diversified valuable products with Csp³-B and Csp²-B bonds obtained simultaneously with B₂pin₂ or portrays alkenyl-migrative module and excellent E/Z selectivity with alkenylBpins.

与成熟的自由基芳环迁移相比，杂原子自由基迁移和烯基自由基迁移仍然具有挑战性。在此，开发了一种基于芳香骨架通过四配位硼物质的光诱导远程自由基迁移反应。在这项工作中，市售的二硼试剂（B ₂ pin ₂）或烯基硼（alkenylBpin）在单容器反应中在锂试剂的介导下与邻溴苯乙烯及其类似物发生反应。该过程通过分子内环状过渡态经历有趣的 1,4-、1,5- 或 1,6- 远程自由基迁移，从而引入大量硼迁移或烯基迁移化合物。特别是1,6-自由基迁移反应以前从未有过报道。该协议具有易于获得的起始材料、高原子经济性、广泛的底物范围和多样化的有价值的产品，与B ₂ pin _{2同时获得的 Csp} ³ -B 和 Csp ² -B 键或描绘了烯基迁移模块和优异的E/Z选择性烯基Bpin。
