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
diastereoselective radical 1,5 phenylmigration reactions fromsilicon in diarylsilyl ethers to various C-centered radicals to form the corresponding 3-phenylated alcohols are described. Functionalized aryl groups can also be transferred. The effect of the variation of the attacking radical on the aryl transfer reaction is discussed. Best results are obtained for the phenylmigration to nucleophilic secondary
