Arylation of arylmagnesium halide etherates by aryllithium provides a convenient method of preparing ar2Mg(Et2O)2 or Ar2Mg(THF)2.The ether complexes can be completely desolvated but the THF complexes cannot.Mixed diarylmagnesium tetrahydrofuranates, Ar¹Ar²Mg(THF)2, although coordinationally saturated, have 1H and 13C NMR spectra which suggest that they are fluxional.
