合成了八种新的四氟硼酸二甲基苯基锍，用元素分析和核磁共振对其结构进行了表征。研究了以CDCl~3为溶剂，NMR位移试剂Eu(fod)~4^-对所合成锍盐的^1H和^1^3C NMR的影响。结果表明，Eu(fod)~4^-是一个对锍盐非常有效的位移试剂，且Eu(fod)~4^-对二甲基苯基锍盐之甲基的^1H和^1^3C NMR的位移呈线性关系。

Eight kinds of new dimethylphenylsulfonium tetrafluoroborates are synthesized and their structures are characterizatized by elementary analysis and nuclear magnetic resonance. The effect of ^1H and ^1^3C NMR spectra of sulfoium salts by NMR shift reagent Eu(fod)~4^- is studied in solvent CDCl~3. The results show that Eu(fod)~4^- is an effective NMR shift reagent for sulfonium salts and ^1H NMR spectra of methyl shift varies linearly with ^1^3C NMR spectra of methyl shift in dimethylphenylsulfonium salts in the presence of NMR shift reagent Eu(fod)~4^-.
