Abstract

The present entitled thesis “Some Substitution Reactions of Aryl 2,4-dinitronaphthyl
Ethers with Amines: Kinetics and Theoretical Studies”
The thesis follows the logical thought process of the organic synthesis, the initial challenge
was not only to synthesize new naphthyl derivatives but to also, enabling the investigation
of the substrate and the products using kinetics and computational tools. The thesis
comprises four chapters:
The first chapter covers the literature survey on the important publications of different
types of nucleophilic aromatic substitution reactions and the effect of the substrates, solvent,
nucleophiles and leaving groups on the mechanism of nucleophilic aromatic substitution
reactions. The survey also includes molecular modeling of mechanisms for SNAr reactions.
The second chapter is devoted to the experimental part of this investigation. The
preparations of the target compounds and purification of the solvent are included. Different
spectral measurements such as UV-Vis, IR, 1H NMR, elemental analysis were used to assign
the structure of prepared compounds. The equations used for determination of the reaction
rates and calculation of activation parameters: energy of activation (Ea), Enthalpy of
activation (ΔH#), Entropy of activation (ΔS#) and free energy of activation (ΔG#) were also
shown. Also, this chapter contains the method of calculation used in theoretical studies
The third chapter includes the results of the present work that collected in tables and
presented in figures for kinetics and theoretical parts.
