| 摘 要： | 本文在四氯化碳介质中考察了苯对1,1-二甲硫基-1]-烯基丙二酸二甲酯的溶剂效应,观察到标题化合物分子内的甲基和溶剂苯的化学位移随着苯的摩尔分数增加而逐渐移向高场,溶剂苯的共振吸收峰是一个尖锐的单峰,同时发现了标题化合物分子中甲基和溶剂苯的化学位移值与混合溶剂苯的摩尔分数呈线性关系.

| Abstract: | This article studies the solvent effect of benzene on dimethyl dimethylthiomethylenemalonate in carbon tetrachloride. It was found that chemical shifts of the methyl protons of the title compound and that of benzene move to upfield gradually, as the mole fraction of benzene in the mixed solvent increases, meanwhile the resonance absorption line of the solvent of benzene is a sharp single line. At the same time, it was found that the chemical shifts of the methyl protons of the title compound and that of benzene in the mixed solvent show linear relation ship with the mole fraction of benzene in the mixed solvent. |
