摘要: 1. The199Hg chemical shifts in the series PhHgOCOC6H4R correlate with polar constants of substituants R. The carboxylate group weakens quite considerably transfer effect substituents, comparison PhHgC6H4R. influence strongly solvating solvents on δHg is comparable to effects substituents. 2. For the199Hg NMR spectra mixtures these compounds, temperature and concentration dependences are observed, indicating intermolecular exchange benzoate fragments. An estimate has been made activation barrier process for a binary mixture 4-ClC6H4COOHgPh 4-MeOC6H4COOHgPh THF.
