Reactions of perfluoroaromatic compounds with ethereal solutions of methylmagnesium iodide in the presence of silver(I) and copper(I) salts

The reactions of hexafluorobenzene, octafluorotoluene, decafluorodiphenyl, and octafluoronaphthalene with ethereal solutions of methylmagnesium iodide in the presence of AgCl or CuI gave the products of the methylation and 1-ethoxy-ethylation of the perfluorinated substrates, whose formation has been suggested to occur with participation of free radicals. Substitution of fluorine atoms by the 1-ethoxyethyl radicals in C6F5CF3 and C6F5C6F5 proceeds with predominant para-orientation; in C10F8, 1- and 2-orientations take place to an equal extent, whereas the methyl radicals attack mainly the 1-position of octafluoronaphthalene and show a low selectivity in the reaction with octafluorotoluene.
