Abstract
The reactivity indexes of the neutral, cationic, anionic, and dipolar forms of 4-hydroxyisoquinoline, calculated by the molecular orbital method using dynamic and static approximations, were compared with the experimental data on electrophilic substitution reactions in various media. Good agreement between the experimentally found orientations (3> 1>8, 7, 6, 5) and the localization energies and boundary densities was obtained. The reactivity indexes of the neutral form of 4-hydroxyisoquinoline were calculated by the Pariser-Parr-Pople method.
