| Abstract: | Arylation of arylmagnesium halides or magnesium 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. |
