A new method for the preparation of 2,3-diaryl-1,1-difluoro-1,3-butadienes

, p. 2261 - 2270 (2001)
Reactions of 1-trifluoromethyl-1,2-diarylvinyl sulfones 3 with aryllithium afforded aryl substituted adduct 4. Bromination of 4 with NBS, followed by debromofluorination with Mg, provided 2,3-diaryl-1,1-difluoro-1,3-butadienes (6) in good yields.
