Verfahren zur Herstellung von Fluor- oder Chlorfluor-Vinylverbindungen

Process for producing unsaturated fluorinated compounds, and more particularly for obtaining compounds containing at least one fluo-vinyl or chloro-fluo-vinyl group, characterized by providing the treatment of an iodo-vinyl derivative containing a fluorine atom bonded to the an iodinated carbon atom and two fluorine atoms or one fluorine atom and one chlorine atom or two chlorine atoms linked to the second carbon atom, with a compound corresponding to formula i-rf, chosen from the group consisting of fluorinated hydrocarbons aromatics, saturated aliphatic fluorinated hydrocarbons and unsaturated aliphatic fluorinated hydrocarbon radicals, in the presence of copper bronze at a temperature between the limits of 100º and 200ºc.
