J. Burdon et al., THE HYDROFLUOROCARBON 1,1,1,2-TETRAFLUOROETHANE (HFC-134A) AS A READYSOURCE OF TRIFLUOROVINYLLITHIUM, Chemical communications, (1), 1996, pp. 49-50
Trifluorovinyllithium has been synthesised in high yield from 1,1,1,2-
tetrafluoroethane (HFC 134a) by treatment with butyllithium at -78 deg
rees C, and then treated with a variety of electrophiles in one-pot re
actions.
