Annotation:

Halogenation, alkylation, and acylation of benzene, for example, are carried out in the presence of so-called Friedel-Crafts catalysts. To understand the catalyst's role, it is necessary to understand the reaction mechanism, which is well studied, yet much about its operation remains unclear. What happens to the reactants and their behavior in the reactions are interpreted differently. To better understand the mechanism of these reactions, the crystal chemical theory of heredity in inorganic nature (CCHI) is applied in this work. Thus, the analysis of benzene substitution reactions during halogenation, alkylation, and acylation involving the chemical compounds FeBr3OE and AlCl3OE, which, according to the KHTN, are inorganic compounds with a stable OE configuration with an AN = 6, predicts their catalytic activity. The catalytic activity of the less stable complex ion intermediates formed during these reactions with a TE configuration and an AN = 4 is also confirmed.

Keywords: halogenation, alkylation, acylation, benzene, crystal chemical theory of heredity.
