Spectroscopic study of a series of phenylmercury derivatives of nitroanilines

1. The sequence of changes in the electron-donor properties of the following groups in p-nitroanilines and their PhHg derivatives was established from the positions of the long-wave bands in the electron spectra and the νasNO2 frequencies and integral intensities of the νAr and νsNO2 bands in the IR spectra: 2. The electron-donor properties of the XHgPh groups in phenylmercury derivatives of p-nitrothiophenol, p-nitrophenol, and p-nitroaniline change in the following order: SHgPh < OHgPh nitroaniline; the Hg atom, in the o-nitroaniline derivative. 4. A quantitative evaluation of the complexing process with DMSO and dissociation in DMSO is given for the compounds studied.
