present a new unified concept for C−C bond formation under redox‐neutral conditions. Our strategy hinges upon interception of a vinyl cation with a sulfoxide resulting in simultaneous C–C and C−O bond formation and arylation. A range of structurally diverse vinyl cations are generated in situ in the presence of a sulfoxide, resulting in hydrative arylation, direct arylation of enol triflates and interrupted
在这里,我们提出了在氧化还原中性条件下形成C-C键的新统一概念。我们的策略取决于乙烯基阳离子被亚砜截留,导致同时的C–C和C–O键形成和芳基化。在存在亚砜的情况下,会在原位生成一系列结构多样的乙烯基阳离子,从而导致水合芳基化,烯丙基三氟甲磺酸酯的直接芳基化和中断Meyer-Schuster重排。机理研究表明,瞬态乙烯基阳离子中间体和结构特征(使其稳定)起着至关重要的作用。还介绍了反应产物在合成中的应用。
