Abstract
To evaluate the reactivity of new difluoroaromatic compounds in nucleo philic 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 i n the F-19 NMR spectra was established.
