Conclusions

  1. 1.

    In the case of polyfluorinated olefins and allyl cations a tendency has been observed for increasing direct13C-19F spin-spin coupling constant values with increasing positive charge on the sp2-hybridized carbon atoms.

  2. 2.

    The13C-19F spin-spin coupling constants for C1 atoms in 1-substituted polyfluorinated olefins and allyl cations also increase with decreasing electronegativity of the heteroatom substituent, but this effect is greater in all cases for cations compared to the corresponding olefins.
