Abstract (en)
[origin: WO9505353A1] Alternatives to chlorofluorocarbons are provided by the inventive process for synthesizing fluorine-containing products RCFbHc+a-1Hf+d-1FeCR' which may optionally be carried out without the isolation of any intermediate in a single reactor or a series of reactors. The process comprises combining chlorine-containing reactants RCClaFbHc and R'CCldFeHf in the presence of hydrogen and at least one catalyst. R and R' are chosen from the group consisting of halogens, halogenated hydrocarbons, and hydrocarbons, and at least one of R and R' contains fluorine, a and d are integers from 1 to 3, b, c, e, and f are integers from 0 to 2, the sum of a, b, and c is 3, and the sum of d, e, and f is 3, and further treating the coupled products in the presence of an optional catalyst with hydrogen or a fluorinating agent.
