Transition-Metal-Free Aryl–Heteroatom Bond Formation via C–S Bond Cleavage

Aryl–heteroatom bonds (C–Het) are almost ubiquitously present in chemical molecules. However, methods for diverse C–Het bond formations from a simple substrate are limited. Herein, we report a convenient and efficient C–S bond transformation of aryl sulfoniums to various C–Het bonds (C–O, C–S, C–Sn, C–Si, C–Se) in the absence of any transition-metal catalyst. These reactions proceeded in mild conditions with a wide substrate scope.
