Abstract A convenient route for the synthesis of difluoromethylene-functionalized compounds from chlorodifluoroacetic acid has been investigated. Bis (chlorodifluoroacetyl) peroxide, which was synthesized from chlorodifluoroacetic acid via its acid anhydride, was found to be a good reagent for the chlorodifluoromethylation of electron-rich aromatic compounds and olefins. The chlorine atom of the chlorodifluoromethylated compounds, ...
