Conclusions

  1. 1.

    In a comparative Investigation by the19F NMR method of two series of model compounds of the type of ArQN(SO2Ph)C6H4,F-4 (Q=Hg, CH2), it was established that the Hg-N binuclear bridge grouping (BNG) possesses a greater transmission capacity (TC) than the CH2-N BNG.

     
  2. 2.

    The efficiency of the transfer of the electronic influence of substituents to an indicator F atom through the Hg-N BNG depends substantially on the direction of transmission.

     
  3. 3.

    The decrease in the TC of the Hg-N BNG in coordinating solvents is the result of both dipole-dipole and coordination interactions with the solvent the contributions of which are practically equal.
