Homolytic substitution at the sulfur atom of beta-(phenylsulfanyl)vinyl radicals, obtained by radical reaction of benzenethiol with easily accessible alkyl 4-pentynyl sulfides, is a mild, effective, tin-free route for the generation of all types of alkyl radicals. This protocol can be employed in reductive defunctionalizations as well as cyclizations onto both electron-rich and electron-poor C-C double
通过苯硫醇与易于获得的烷基4-戊炔基硫化物的自由基反应获得的β-(苯基硫烷基)乙烯基自由基的硫原子上的均质取代是一种温和,有效,无锡的生成所有类型烷基的途径。此协议可用于还原性去官能化以及富电子和贫电子CC双键的环化反应。
