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 transition metal catalyst is required and the reaction takes
描述了一种通过脱硫氯原子转移自由基加成至未活化烯烃的有效方法。该反应基于使用容易获得的磺酰氯作为起始原料和廉价的自由基引发剂,例如偶氮二异丁腈(AIBN),二叔丁基二氮烯(DTBD)和二月桂酰过氧化物(DLP)。不需要过渡金属催化剂,该反应在温度≤85°C的温和条件下进行。
