A stereospecific synthesis of fluorinated enynes and dienes was performed through palladium-catalyzed condensation of 1-bromo-2-fluoroalkenes, synthesized either through “BrF” addition to the corresponding alkynes or through bromineaddition and HBr elimination on fluoroesters, with monosubstitued alkynes or alkenes.

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.
