本文合成了一系列共13种芳基-8-喹啉氧基汞化合物,其中12种为新化合物, 经IR,^1H NMR和元素分析鉴定了其组成与结构,紫外光谱研究表明分子中存在有N→Hg分子内配位.提出了溶剂效应对紫外光谱性质和N→Hg分子内配位影响的机理. 核磁共振氢谱表明取代基仅影响汞-苯环质子的化学位移,说明共轭效应未通过分子内配位贯穿于整个分子.^1^9^9Hg化学位移值与Hammett-Brown常数σ^+间存在有良好的线性关系

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

Key words: INFRARED SPECTROPHOTOMETRY, ELEMENTAL ANALYSIS, PROTON MAGNETIC RESONANCE SPECTROMETRY, SOLVENT EFFECT, CHEMICAL SHIFT, HYDROXY QUINOLINES
