Effect of ^1H and ^1^3C NMR spectra of sulfonium salts by NMR shift reagent Eu(fod)~4^-

Abstract

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^-.
