Application of Sulfur Ylides in 1,2-Difunctionalization of Arynes via Insertion into a C–S σ‑Bond

Abstract

A novel reactivity of sulfur ylides has been demonstrated in a transition-metal-free protocol to access <i>ortho</i>-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
