Conclusions

  1. 1.

    We determined the chemical shifts in the31P NMR spectra of the compounds\((C_2 H_5 O)_2 P(O)SX (X = (CH_2 )_m \mathop S\limits^ + (CH_3 )C_2 H_5 \), (CH2)mSC2H5 (m=2–4 and 6)) and CnH2n+1 (n=6, 8), and obtained a linear correlation between δp and the σ* constants of the X substituents.

     
  2. 2.

    The induction constants of the charged substituents, which were obtained from the rate of the inter-ionic reactions at a high ionic strength of the medium, constitute a single scale with the σ* constants for the uncharged electronegative substituents.
