This reactivity and stability work was performed on six (6) Thiazoline derivatives using density functional theory at the B3LYP/6-31+ G (d, p) level. The aim was to determine the electrophilic and nucleophilic sites and the chemical behaviour of thiazolines. To do this, we calculated the fukui reactivity parameters (f+; f-), as well as the conceptual DFT reactivity parameters. The analysis of local descriptors and the molecular electrostatic potential map identified the nitrogen (N) atoms of the Thiazoline ring as the preferred electrophilic attack site (nucleophilic site) for the compound series. Moreover, the Natural Population Analysis (NPA) also corroborated this same information, that is to say the sulfur atoms (S) are electrophilic sites and the nitrogen atoms the nucleophilic sites of the compounds studied. Also, the sulfur atones that bind the linker were designated as the nucleophilic attack site (electrophilic site). The study of the boundary molecular orbitals, including energy gap (ΔE), electronegativity (χ), chemical hardness (η), and electrophilicity index (ω) allowed the chemical reactivity of Thiazoline derivatives to be described from the molecular properties. Thus, the Th3 molecule is the most stable, least reactive and hardest. Moreover, the Th3 compound is the one which gives the least electrons on all the studied molecules.
