A CONVENIENT SYNTHESIS OF FLUORINATED α,β-UNSATURATED AMIDES
Pentafluorophenylated or p-chloro-tetrafluorophenylated α,β-unsaturated amides could be synthesized by the reaction of fluorinated arsorane, generated in situ from methylenetriphenylarsorane and hexafluorobenzene or chloro-pentafluorobenzene, with α-bromoacetamides in good yields giving E-isomer exclusively.
