The construction of fluorocarbene ligands within the coordination sphere of transition metal complexes using sequential nucleophilic and electrophilic addition to a vinylidene complex is described. Reaction of [Ru(η5-C5H5)(dppe)(CCPhF)][N(SO2Ph)2] with [NMe4]F results in nucleophilic attack of fluoride at the metal-bound carbon of the vinylidene ligand to give alkenyl complex [Ru(η5-C5H5)(dppe)(-CFCFPh)]. Subsequent eletrophilic fluorination with N-fluorobenzenesulfonimide (NFSI) results in the formation of the fluorinated carbene complex [Ru(η5-C5H5)(dppe)(CF-CHFPh)][N(SO2Ph)2]. The fluorocarbene complexes undergo rearrangement to liberate free fluorinated alkenes, a process governed by the choice of solvent and anion, representing a new metal-mediated route to fluorinated alkenes from alkynes.

(Z)-2-chloro-1,2-difluoro-1-iodoethene and (E)-2-chloro-1,2-difluoro-1-iodoethene successfully form stable zinc reagents. The zinc reagents successfully undergo Negishi coupling reactions with substituted aryl iodides to form (E)- and (Z)-1-chloro-1,2-dif

An overall retention of configuration is observed during the chlorodesilylation of (Z)-1-silyl-1,2-difluoroalkanes, carried out in the presence of fluoride ion and in a polar solvent.
