Abstract

The control of noncovalent interactions has been increasingly used to direct the regioselectivity of reactions involving unactivated arenes. Pd-Catalyzed meta-selective C-H olefination and Ir-Catalyzed C-H borylation has been highlighted in the specialized literature. Despite the growing interest in the description and control of noncovalent interactions in regioselectivity, there are few studies that make use of computational methodologies in detailing the interactions present and how ligands, solvents, substrates and even the metallic center could be specifically designed according to the products of interest. Therefore, the main objective of this research project is to carry out a detailed computational study, mainly using methods based on quantum mechanics, of the meta-selective C-H olefination/borylation reactions directed by noncovalent interactions. It is expected that, based on the results obtained, we will be able to suggest modifications in the reaction protocols, as in relation to the design of new ligands, as well as the participation of different substrates, solvents and transition metals.
