  under similar conditions and longer reaction times (48 h) to give pure (E)-monofluoroenynes in excellent yields (78–89%). Thus, E/Z mixtures of 1-bromo-1-fluoroolefins could be kinetically separated into (Z)- and (E)-monofluoroenynes. This methodology provides a simple one-step unequivocal route to the isomerically pure (Z)- and (E)-monofluoroenynes from the readily available 1-bromo-1-fluoroolefins.

  Au(I) fluorido SPhos complexes react with alkynes to yield metal-fluorovinyl species. Addition of HCl resulted in protodeauration with retained stereoselectivity. Various Au(I) complexes were then compared in their ability to catalyze hydrofluorination reactions of 1-phenyl-1-propyne employing Et3N ⋅ 3HF as HF source.

  The efficient preparation of alpha-fluoro-beta,gamma-alkenylphosphonate 3, via catalytic hydrogenation of (alpha-fluoropropargyl)phosphonate ester 1, is described. Conjugated fluoroenynes 4 have been synthesized using a modified Horner Wadsworth Emmons (HWE) olefination of aldehydes or ketones and 1 in relatively good yields. Yields were lowered because of the formation of alpha-fluoro-gamma-hydroxyallenylphosphonate 5 during the reaction. The nature of the counterion was very important in the outcome of the HWE reaction; better yields of fluoroenynes were obtained when a potassium base was used instead of a lithium base.
