Abstract
The application of Molecular Orbital theory to aromatic substitution has been developed extensively in literature. Until recently, calculations of reactivities in aromatic substitution have been based either on static indices of the reagents or on the relative stabilities of transition states. However, most of the Molecular Orbital calculations to determine reactivities in aromatic substitution reactions haven't considered the dynamically changing systems.|By realizing this problem in the calculation with a single model of the transition state in every kind of reaction we were rather interested in the dynamically changing system - the reaction pathway from reactant to intermediate through the transition state.|The purpose of our work was to construct the energy profile for transformation of reactants to intermediates in electrophilic aromatic substitution and to determine the reactivities based on that energy diagram.
