Arylmercury Compounds. Part VI. Asymmetric Diarylmercury Compounds

Abstract

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, lR, 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.

Mass spectrometry of organomercurials

“…Peaks due to the molecular ions of organomercury compounds with virtually all possible combinations of substituents in the given system (Ar3HgAr2, Ar'HgAr3, ArlHg, AriHg, Ar'HgAr,, etc.) can be detected in the mass spectra of mixtures of diarylmercury derivatives; for example, Ar'HgAr' and Ar3HgAr4 (15,25,26).…”
