This method using thiophenol proved to be very efficient
with a wide range of substrates but required high dilution
(10\12m of substrate) and the slow addition of thiophenol with
a syringe pump [Eq.(1)].Some limitations were also noticed,
with some substrates undergoing slow hydrogen transfers.For
example,the generation of a nonstabilized acyclic secondary
alkyl radical proved to be difficult because of the reduction ofthe alkenyl radical and its cyclization onto the phenylthio
group,thus leading to benzothiophene derivatives [Eq.(2)].[5]

已经证明,使用苯硫酚的方法对许多反应物非常高效,但需要高度稀释(反应物的10 2m错误字符!可能是一个分数) ,且苯硫酚需要用注射器泵缓慢加入[反应式(1)].我们也注意到了一些反应物的氢原子缓慢转移的局限性.如不稳定的非环状次生烷基的合成非常困难,这是由于烷基消去反应及其在苯硫基上成环造成的,因此导致了苯并噻吩类衍生物的生成[反应式(2)][5].
