Direct perfluoroalkylation of non-activated aromatic C–H bonds of phenols
A simple procedure for the perfluoroalkylation of the aromatic ring of phenols under mildly basic conditions is described. Treatment of a variety of phenols with perfluoroalkyl iodide in the presence of the radical initiator V-70L and Cs2CO3 provided the corresponding perfluoroalkylated products in moderate to good yields. Generally, the reaction proceeded smoothly at room temperature to yield regioselectively
描述了在温和碱性条件下苯酚芳环全氟烷基化的简单程序。在自由基引发剂V-70L和Cs 2 CO 3的存在下用全氟烷基碘处理各种酚,以中等至良好的产率提供了相应的全氟烷基化产物。通常,反应在室温下平稳进行,得到区域选择性的全氟烷基化产物。
