A NEW SYNTHESIS OF PERFLUOROAROMATIC GRIGNARD REAGENTS

Perfluoroarylmagnesium compounds have been synthesized directly from completely fluorinated aryl compounds (e.g., hexafluorobenzene, decafluorobiphenyl, octafluorotoluene and octafluoronaphthalene) through their reaction with ethylmagnesium bromide and certain transition metal halides (CoCl2, FeCl2, NiCl2, CuI, TiCl4, PdCl2, RhCl3 and AgCl). The yields of the perfluoroarylmagnesium compound vary with the type of perfluoroaryl substrate and metal halide. The perfluoroarylmagnesium compounds thus formed undergo typical Grignard reactions. © 1969.
