Thirteen arylmercuric quinolin-8-olates were synthesized and characterized by IR, 1H NMR and elemental anal., of which twelve are new compounds UV spectra showed that an intramol. N ?Hg coordination exists in the mols. examined The mechanism of the solvent effect on the UV spectral properties and on the N ?Hg coordination was proposed. 1H NMR spectra indicated that the substituents influence only the chem. shifts of the Hg-Ph protons, which reveal that the conjugation does not spread throughout the whole mols. via the intramol. coordination. A good linear relation was found between the 199Hg chem. shifts and the Hammett-Brown s+ constants
