【摘要】 在四氯化碳介质中考察了苯对标题化合物的核磁共振谱的溶剂效应．观察到标题化合物分子中的两个甲硫基和混合溶剂中的苯的共振吸收峰随着苯的摩尔分数增加而逐渐移向高场，而且两个甲硫基向高场移动程度不同，ASIS值也随苯的摩尔分数增加而增加，得到了所有化学位移值和ASIS值与苯的摩尔分数呈线性关系，尝试用溶剂化作用解释了标题化合物的ASIS效应．更多还原

【Abstract】 This article studies the solvent effect of benzene on the NMR sprctra of title compound in carbon tetrachloride. It has been found that the chemical shifts of the resonance absorption lines of the two methylthio groups in title compound and that of benzene in the mixed solvent move upfield gradually,as the mole fraction of benzene in the mired solvent increases. The rates of upfield shifts of the reso-nance absorption lines of the two methylthio groups are different, and as the mole fraction of benzene increases, the ASIS increases. All the chemical shifts and ASIS show linear relationships with the mole fraction of benzene in the mixed solvent. It has been tried to use the solvation to explain the ASIS effect of benzene on title compound.更多还原
