A mild and transition-metal-free synthesis of β-keto arylthioethers has been developed by the aryne triggered [2,3] Stevens rearrangement of allylthioethers. The key sulfur ylide intermediate for the rearrangement was formed by the S-arylation of allylthioethers with arynes generated from 2-(trimethylsilyl)aryl triflates using CsF. Later, the reaction products are converted into valuable heterocycles in two steps.
一种温和的、无需过渡金属的β-酮芳硫醚的合成方法，通过芳炔引发的烯丙基硫醚[2,3]史蒂文斯重排反应实现。重排过程中的关键硫叶立德中间体是通过用氟化铯（CsF）处理 2-（三甲基甲硅烷基）芳基三氟甲磺酸酯生成的芳炔与烯丙基硫醚的 S-芳基化反应形成的。随后，两步反应可将产物转化为有价值的杂环化合物。
