Abstract

Pi-interactions can be used to approach aromatics and obtain self-association, charge transfer and catalysis systems. This project proposes the synthesis of naphthalene diimide-based molecules for use as a catalyst for the amination reaction of halo-benzenes and other derivatives. The composition of the catalyst molecule will have acid groups (ammonium and phosphonium) and pi-system for aromatic interaction. The system is expected to be efficient for the aromatic substitution reaction in aqueous medium, alcohols and/or aprotic dipolar solvents. NMR, infrared, masses and elemental analysis will be performed. (AU)
