An efficient protocol for [2,3]-sigmatropic rearrangement of allyl and propargyl thioethers is reported. The key sulfonium ylide intermediate is in situ formed via S-arylation of arynes. This transitionmetal-freemethod allows for ready access to a wide array of functionalized thioether derivatives in good to excellent yields.
