我们证明了顺序歧化反应可以使两个或四个电子空穴在高价碘中心选择性聚集。阳极生成的碘基自由基歧化得到碘基苯衍生物。随后的碘基苯歧化可被触发以提供对碘基苯的接触。这些结果证明了选择性和顺序歧化化学在单电子电位下的多电子氧化。
We demonstrate that sequential disproportionation reactions can enable selective aggregation of two- or four electron–holes at a hypervalent iodine center. Disproportionation of an anodically generated iodanyl radical affords an iodosylbenzene derivative. Subsequent iodosylbenzene disproportionation can be triggered to provide access to an iodoxybenzene. These results demonstrate multielectron oxidation at the one-electron potential by selective and sequential disproportionation chemistry.
