摘　　要：本文以芳基氯化汞和苯硫酚或对甲基苯硫酚在乙醇中反应合成了两个系列共32种芳汞基芳基硫化合物,其中22种为新化合物。研究了这些化合物的紫外吸收光谱和核磁共振氢谱,所得结果表明,对此两个系列的标题化合物,在△λ_max与Hammett取代基常数σ_p之间有良好的线性关系,但共轭作用未完全通过硫原子贯穿到整个分子。也对取代基对~1H NMR的影响进行了研究。Two series of thirty two aryl arylmercury sulfides were synthesized by the reac-tion of arylmercuric chloride with thiophenol or 4-methylthiophenol in ethanol. Twenty twoof them are new compounds. The UV and ~1H NMR spectra of these compounds were studied,the results obtained show that a good linear relationship exists between the △λ_(max) and Ham-mett substituent constant σ_p both for the two series of the title compounds. but the conju-gation does not entirely extend over the sulfur atom to the whole molecule. The substituenteffect on ~1H NMR was also studied.
