Stereoselective aryl migration reactions from sulfur in sulfonates and sulfonamides to C-centered radicals are reported. The 1,5-aryl migration from sulfur 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
报道了从磺酸盐和磺酰胺中的硫到 C 中心自由基的立体选择性芳基迁移反应。从硫到不同取代的 C 中心自由基的 1,5-芳基迁移可以以高产率和选择性进行。官能化的芳基也可以通过这种新方法转移。提出了解释反应立体化学结果的模型,并讨论了该反应的一些机理方面。从亚磺酸盐中的硫到碳自由基的芳基迁移反应效率较低,并且根本没有观察到芳基亚砜中的相应迁移。(© Wiley-VCH Verlag GmbH, 69451 Weinheim, Germany, 2002)
