In the presence of BF,. OEg,(perfluoroalky1) lithiums generated in situ from the reaction of primary perfluoroalkyl iodides and MeLi-LiBr reacted with imines, azines, and nitrones to afford perfluoroalkylated nitrogen-containing compounds in moderate to good yields. This method was successfully applied to the preparation of a (perfluoroalky1) glycine and optically active perfluoroalkylated amines.
