Arylmercury Compounds. Part VI. Asymmetric Diarylmercury Compounds

Asymmetric diarylmercury compounds were produced together with symmetric products via a symmetrization process. The asymmetric products could not be isolated from the reaction mixture and their existence was indicated through different analyses (mp, IR, PMR, mass spectra, elemental analysis and DTA). The asymmetric products were shown to be unstable and to disproportionate into two symmetric compounds at elevated temperatures, and in organic solvents even at room temperature.
