Metal-Free, Radical Addition to Alkenes via Desulfitative Chlorine Atom Transfer

摘要

An efficient method for radical additions to unactivated alkenes via desulfitative chlorine-atom transfer is described. The reaction is based on the use of readily available sulfonyl chlorides as starting materials and cheap radical initiators such as azobisisobutyronitrile (AIBN), di-tert-butyldiazene (DTBD), and dilauroyl peroxide (DLP). No transi-tion metal catalyst is required and the reaction takes place under mild conditions at temperatures ≤ 85 °C.
