Perfluoroalkylation of pyridine and itsderivatives was achieved by reacting with perfluoroalkyl iodides or bromides in the presence of rongalite under mild conditions.
吡啶及其衍生物的全氟烷基化是通过在温和的条件下在钙铝矾石的存在下与全氟烷基碘或溴化物反应来实现的。

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。

Perfluoroalkylation of some nitrogen-containing heteroaromatic compounds such as pyrrole, pyridines, quinoline and isoquinoline has been achieved by reacting with perfluoroalkyl iodides or bromides in the presence of Rongalite under mild conditions. The distribution of isomers formed was consistent with a radical reaction mechanism.
