在可见光存在下,乙烯基硼酸酯与缺电子的烷基碘反应生成硼酸酯,其中产生了两个新的 CC 键。该反应通过将缺电子烷基自由基加成到硼酸乙烯酯上,然后与另一个烷基碘分子进行电子转移,继续链并引发 1,2-金属酸盐重排而发生。在许多情况下,使用光氧化还原催化剂可显着提高产率。自由基前体的范围包括α-碘酮、酯、腈、伯酰胺、α-氟化卤代乙酸酯和全氟烷基碘。

Vinyl boronates react with electron-deficient alkyl iodides in the presence of visible light to give boronic esters in which two new C-C bonds have been created. The reaction occurs by radical addition of an electron-deficient alkyl radical to the vinyl boronate followed by electron transfer with another molecule of alkyl iodide, continuing the chain, and triggering a 1,2-metalate rearrangement.
