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, thus prepared, exchanged hydrogen and allyl groups by reaction with tributyltin hydride and allyltributyltin, resp., under radical conditions.
Journal of Fluorine Chemistry published new progress about 53731-26-3. 53731-26-3 belongs to naphthyridine, auxiliary class Difluoromethyl,Fluoride,Naphthalene, name is 1-(Difluoromethyl)naphthalene, and the molecular formula is C8H11NO, Safety of 1-(Difluoromethyl)naphthalene.
