Boron Trifluoride-Assisted Ziegler–Zeiser Reaction of Perfluoroalkyllithiums, An Efficient Synthesis of Perfluoroalkylated Heterocycles
Quinoline, isoquinoline, quinaldine, phthalazine, and quinoxaline are all found to react smoothly with perfluoroalkyllithiums in the presence of BF3·OEt2, giving the corresponding perfluoroalkyl addition and/or substitution products in good yields. Perfluoroalkylation occurs at the carbon atom next to the nitrogen.

The reaction of pyridine and its derivatives with sodium perfluoroalkanesulfinates (RFSO2Na) in the presence of Mn(OAc)3 is reported. Pyridines react with this reagent system readily to give the corresponding perfluoroalkylated products as a mixture of isomers with moderate yield. However, reaction of quinoline and isoquinoline under similar conditions gives the C(5)- and C(8)-substituted products
据报道,在Mn(OAc)3存在下,吡啶及其衍生物与全氟烷基亚磺酸钠(RF SO 2 Na)反应。吡啶容易与该试剂系统反应,以中等收率得到相应的全氟烷基化产物,为异构体混合物。但是,喹啉和异喹啉在相似条件下的反应会在区域选择性地产生C(5)-和C(8)-取代的产物。
Single-stage synthetic route to perfluoroalkylated arenes via electrocatalytic cross-coupling of organic halides using Co and Ni complexes
A new method of single-stage synthesis of perfluoroalkylated arenes via cross-coupling of bromo (in some cases, chloro) arenes and heteroarenes (derivatives of benzene, pyridine and furan) and organic perfluoroalkyl halides involving complexes of nickel and cobalt in low oxidation state with α-diimines under mild conditions was proposed. Perfluoroalkylated products are obtained in good yields in the
