Trifluorovinyllithium (from 1,1,1,2-tetrafluoroethane [HFC-134a]) reac
ted with 2-trifluoromethylaniline at -78 degrees C to give 1,2,3-trifl
uoroquinoline in moderate to good yield. In a similar reaction, 1-chlo
rodifluorovinyllithium (from 1-chloro-2,2,2-trifluoroethane [HCFC-133a
]) yielded 2-chloro-1,3-difluoroquinoline. (C) 1997 Elsevier Science S
