Stereoselective aryl migration reactionsfromsulfur in sulfonates and sulfonamides to C-centered radicals are reported. The 1,5-aryl migration fromsulfur to differently substituted C-centered radicals could be performed with high yields and selectivities. Functionalized aryl groups could also be transferred by this new method. A model to explain the stereochemical outcome of the reaction is presented and some
