Uno, Hidemitsu,Okada, Shin-ichiro,Ono, Tetsushi,Shiraishi, Yasukazu,Suzuki, Hitomi

, p. 1504 - 1513 (2007/10/02)

In the presence of BF3*OEt2, (perfluoroalkyl)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 (perfluoroalkyl)glycine and optically active perfluoroalkylated amines.
