The aromatic perfluoroalkylation catalyzed by a copper(I) salt with bis(perfluoroalkyl)zinc reagents Zn(RF)2(DMPU)2, which were prepared and then isolated as a stable white powder from perfluoroalkyl iodide and diethylzinc, was accomplished to provide the perfluoroalkylated products in good‐to‐excellent yields. The advantages of this reliable and practical catalytic reaction are 1) air‐stable and easy‐to‐handle
制备了铜(I)盐与双(全氟烷基)锌试剂Zn(R F)2(DMPU)2催化的芳族全氟烷基化反应,然后将其作为稳定的白色粉末从全氟烷基碘化物和二乙基锌中分离出来。全氟烷基化产品,收率优良。这种可靠,实用的催化反应的优点是:1)空气稳定且易于操作的双(全氟烷基)锌试剂可以使用; 2)该试剂具有反应性,因此无需活化剂和配体即可简单地进行操作; 3 )不仅可以实现三氟甲基化,而且可以实现全氟烷基化。
