Intramolecular arylation of aryl radicals was mediated by SmI2/HMPA in the presence of i-PrOH to give spirocycles and/or reduced cine-cyclised products, while the reaction in the absence of i-PrOH gave the rearomatised fused rings.
在 i-PrOH 存在下,
SmI2/HMPA 介导芳基的分子内芳基化,得到螺环和/或还原的电影环化产物,而在 i-PrOH 不存在的情况下,反应得到重新芳构化的稠合环。
