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。
Unprecedented Asymmetric Epoxidation of Isolated Carbon-Carbon Double Bonds by a Chiral Fluorous Fe(III) Salen Complex: Exploiting Fluorophilic Effect for Catalyst Design
The first asymmetricepoxidation of isolated carbon–carbon double bonds using an Fe(III)‐centered chiral salen complex is described. This is the first example of novel asymmetric space construction for a catalyst that exploits the intramolecular fluorophilic effect of fluorous tags.
