A novel reactivity of sulfur ylides has been demonstrated in a transition-metal-free protocol to access ortho-substituted thioanisole derivatives by insertion of arynes into a C–S σ-bond in moderate to good yields. The reaction involves the formation of C–C and C–S bonds and consecutive breaking of two C–S bonds under operationally mild reaction conditions.

硫叶立德在C–Sσ-键中插入在1,2-双官能团的芳烃中的应用

通过将芳烃以中等至良好的产率插入C–Sσ键中，可以在无过渡金属的方案中获得新型的硫酰化物反应性，从而获得邻位取代的硫代茴香醚衍生物。该反应涉及在操作温和的反应条件下形成C–C和C–S键以及两个C–S键的连续断裂。
