SYNTHESIS OF FLUORINATED OLEFINS FROM FLUORINATED ALCOHOLS

Disclosed is a process for producing a hydrofluoroalkene, RfCF=CH2 comprising contacting a hydrofluoroalkanol of structure RfCF2CH2OH, with a lewis acid to produce a mixture, diluting said mixture with a solvent to produce a solvent mixture, contacting the solvent mixture with a reactive metal, heating the solvent mixture and reactive metal for a sufficient amount of time to produce a hydrofluoroalkene, and condensing and collecting the volatile products comprising the hydrofluoroalkene, wherein Rf is F, or a fluorine-substituted alkyl group.

Reductive dehalogenation of polyhalofluorocarbons with tributyltin hydride

The reduction of polyhalofluorocarbons, including ClCF2CFClCF2Cl, (ClCF2CFCl)2, ICH2(CF2)3CH2I and vicinal dichloroperfluorocycloalkanes, with tributyltin hydride gave the corresponding hydrofluorocarbons in good to excellent yield.The results are compared with similar reductions with other reducing agents, and to tin hydride reductions of non-fluorinated analogs. - Keywords: Reductive dehalogenation; Polyfluorocarbons; Tributyltin hydride; NMR spectroscopy; Hydrofluorocarbons
