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
