Abstract: | To evaluate the reactivity of new difluroroaromatic compounds in nucleophilic substitution, the positive charges on carbon
atoms of C−F bonds were calculated using the quantum-chemical semiempirical PM3 method. A correlation between the charges
calculated and the chemical shifts in the19F NMR spectra was established.
